* Avoid leaking blackholed register ops in tests (#114287)

Today when we reboot a node in a test case derived from
`AbstractCoordinatorTestCase` we lose the contents of
`blackholedRegisterOperations`, but it's important that these operations
_eventually_ run. With this commit we copy these operations over into
the new node.

* Re-enable ScaledFloatFieldMapperTests.testSyntheticSourceKeepArrays (#114408)

* Default enable cluster state role mapper (#114337)

This PR default-enables cluster-state role mappings as the first part of the mitigation for a regression in ECK introduced by https://github.com/elastic/elasticsearch/pull/107410. 

Prior to this PR, cluster-state role mappings were written to cluster-state, but not read from it. 

With this PR, cluster-state role mappings will be read and used to assign roles to users, i.e. in user role resolution. 

However, they will not be included in the output of the [Get role mappings API](https://www.elastic.co/guide/en/elasticsearch/reference/current/security-api-get-role-mapping.html) yet. Exposing them via API is a target for a follow-up fix.

This type parameter is only needed so that the `.timeout(TimeValue)`

by data streams. Some mappings throw errors as a result of incompatibilities
when trying to merge object fields. Such errors are expected.

This PR applies a temporary patch to fix an issue with ordered and unordered intervals source.
The flattening that is applied in Lucene modifies the final gap preventing valid queries to match.
The fix already exists in Lucene but will be released in Lucene 10.x later this year.
Since the bug prevents the combination of ordered and unordered intervals with gaps, this change applies
a workaround to ensure that the bug is fixed in Elasticsearch 8x.

* ESQL: Delay construction of warnings (#114368)

Delay construction of `Warnings` until they are needed to save memory
when evaluating many many many expressions. Most expressions won't use
warnings at all and there isn't any need to make registering warnings
super duper fast. So let's make the construction lazy to save a little
memory. It's like 200 bytes per expression which isn't much, but it's
possible to have thousands of expressions in a single query. Abusive,
but possible.

This also consolidates all `Warnings` usages to a single `Warnings`
class. We had two. We don't need two.

* Ensure that all rewriteable are called in retrievers (#114366)

This PR ensures that all retriever applies the rewrite to all their rewriteable.
Rewriting eagerly at the retriever level ensures that we don't rewrite the same query multiple times

* Return `_ignored_source` only if explicitly requested via `stored_fields` or `fields` (#114145)

We do not want to return `_ignored_source` with every search hit. Other than being expensive
(especially when there are many ignored fields), it also exposes some implementation details. Anyway, it might
still be useful to have the ability to retrieve it if necessary, at least for debugging purposes. For this
reason we require that it is explicitly requested using `stored_fields` or `fields` and we do not return
it by default or if requested via a wildcard `*` in `stored_fields` or `fields`.

When TransportService fails to send a transport action, it can complete

thread, it will trip the `assertCompleteAllowed` assertion.

* [ML] Upgrade to AWS SDK v2 (#114309)

- Replaced AWS 1.12.740 with 2.28.13
- Removed `aws-java-sdk*` and its transitive dependencies.
- Added `awssdk:bedrockruntime` as an `implementations`, all transitive
  dependencies are added as `api` matching their marked `Compile` in
  maven.
- Added `awssdk:netty-nio-client` as our client implementation, since
  our v1 integration is using the respective Async client.
- Added netty packages as `runtimeOnly` since they are only used during
  runtime.
- Replaced AWS's use of SLF4J-1.7 with our declaration of SLF4J-2.x,
  since SLF4J includes backwards-compatible bindings.
- Migrated all references from the v1 package (`com.amazonaws`) to the
  v2 package (`software.amazon.awssdk`).

Notable changes in the SDK:
- *Result objects are renamed to *Response objects.
- Objects are now immutable and require Builders to set fields.
- Getters no longer have the `get*` prefix, e.g. `getModelId()` is now
  `modelId()`.
- `Future` has been replaced with `CompletableFuture`.
- There is no longer a need to invoke the `IdleConnectionReaper`, this
  is now done when the client is closed.
- Builders have a consumer mutation pattern for modifying many fields at
  once.

Security changes:
- The underlying Builder objects always check to see if the
  `.aws/credentials` and `.aws/config` files exist, even if they are not
  used, so our `plugin-security.policy` now allows reading these files.
- The Builder always checks for the `http.proxyHost` property before
  defaulting to the hardcoded Bedrock URL.

* Simplifying TextSimilarityRankBuilder to operate through the standard QueryPhase (#114567)

* Enable pushing Sort/Filter by ReferenceAttribute down to Lucene, and thereby optimize Sort by ST_DISTANCE (#112938)

The ST_DISTANCE function added in #108764 was optimized for lucene pushdown in a series of followup PRs, but this did not include sorting by distance. Now this is resolved, for two key scenarios, both known to be valued by users:

* Sorting by distance:
    `FROM index | EVAL distance=ST_DISTANCE(field, literal) | SORT distance`
* Sorting and filtering by distance:
    `FROM index | EVAL distance=ST_DISTANCE(field, literal) | WHERE distance < literal | SORT distance`

The key changes required to make this work:
* Add to the EsQueryExec the appropriate sort->_geo_distance sort type
* Enhance PushTopNToSource to understand how to pushdown the sort even when there is an EVAL in between the FROM and the SORT (between the TopNExec and the EsQueryExec in the physical plan).
* Enhance PushFiltersToSource to understand how to pushdown the filter even when there is an EVAL in between the FROM and the WHERE (between the Filter and the EsQueryExec in the physical plan).

A useful bonus feature of this additional EVAL intelligence is that other, non-spatial cases are now also pushed down. In particular EVALs that are simple aliases are considered and pushed down, for both filtering and sorting.

Local benchmark results, very approximate, but show massive improvements for distanceSort and distanceFilterSort, which relate to the two cases listed above.

Benchmark	Query DSL	ESQL before this PR	ESQL after this PR	Comments
distanceFilter	10	5	5	Optimized in #109972
distanceEvalFilter	10	10000	1500	Still slow due to unnecessary EVAL
distanceSort	150	12000	160	
distanceFilterSort	20	10000	24	

NOTE: This enables pushing down sorting by any ReferenceAttribute that either refers to a sortable FieldAttribute, or to an StDistance function that itself refers to a suitable FieldAttribute of geo_point type.

A silly bug has reared its ugly head. Apparently, our dimension

So, this commit adjusts the dim validations so that it is an actual
validation, instead of something that occurs during parsing.

Additionally, I found that our custom formats were not overriding
`getMaxDimensions` correctly. Typically, and in production, this isn't
that big of a deal, but I have found it useful to do this for other
testing purposes (so that we don't have to rely on the perfield codec
for more direct and advanced testing).

* [Failure store - selector syntax] Refactor IndicesOptions builder (#114597)

**Introduction**

> In order to make adoption of failure stores simpler for all users, we
are introducing a new syntactical feature to index expression
resolution: The selector. > > Selectors, denoted with a :: followed by a
recognized suffix will allow users to specify which component of an
index abstraction they would like to operate on within an API call. In
this case, an index abstraction is a concrete index, data stream, or
alias; Any abstraction that can be resolved to a set of indices/shards.
We define a component of an index abstraction to be some searchable unit
of the index abstraction. > > To start, we will support two components:
data and failures. Concrete indices are their own data components, while
the data component for index aliases are all of the indices contained
therein. For data streams, the data component corresponds to their
backing indices. Data stream aliases mirror this, treating all backing
indices of the data streams they correspond to as their data component.
>  > The failure component is only supported by data streams and data
stream aliases. The failure component of these abstractions refer to the
data streams' failure stores. Indices and index aliases do not have a
failure component.

For more details and examples see
https://github.com/elastic/elasticsearch/pull/113144. All this work has
been cherry picked from there.

**Purpose of this PR**

This PR is replacing the the indices options boolean constructor with
the builders. The goal is to give me and the reviewer a very narrow
scope change when we can ensure we did not make any mistakes during the
conversion. Also it will reduce a bit the change list in
https://github.com/elastic/elasticsearch/pull/113144/files.

* SQL: Remove dependency on `org.elasticsearch.Version` (#112094)

This removes SQL's use of `org.elasticsearch.Version` class and usages replaced by `SqlVersion`.

All the currently considered released versions (`7.0.0` to `8.16.0`) have been declared as `SqlVersion` instances. These are still tested against.

The last "known release" (`8.16.0`) is considered the "server compatibility version" and all clients at or past this release are compatible with the server; notably, they can be also on a newer version than server's. 
Clients released before this "server compatibility version" respect existing compatibility requirements (must/can be older up to one major lower, but past `7.7.0`).
The "server compatibility version" will not be updated with newer stack releases (at least not until #112745 is addressed).

Fixes #102689

Fixes https://github.com/elastic/elasticsearch/issues/114613

Those tests were added with `::<type>` casts, which don't work in older versions.

As they aren't testing anything around those casts, I'm replacing them with `TO_<TYPE>()` functions to let them work everywhere.

Since Kibana only needs CCS metadata in ESQL responses from certain well-defined locations,

you specify "profile": true in the ESQL body and if you asked for it will be present in the response
always (it will be written to the .async-search index and you can’t turn it off in later async-search
requests against this particular query ID) and if you didn’t ask for it at the beginning it will never
be present (it will NOT be written to the .async-search index when it is persisted).

The new option is "include_ccs_metadata": true/false.

* ESQL: Speed up grouping by bytes (#114021)

This speeds up grouping by bytes valued fields (keyword, text, ip, and
wildcard) when the input is an ordinal block:
```
    bytes_refs 22.213 ± 0.322 -> 19.848 ± 0.205 ns/op (*maybe* real, maybe noise. still good)
       ordinal didn't exist   ->  2.988 ± 0.011 ns/op
```
I see this as 20ns -> 3ns, an 85% speed up. We never hard the ordinals
branch before so I'm expecting the same performance there - about 20ns
per op.

This also speeds up grouping by a pair of byte valued fields:
```
two_bytes_refs 83.112 ± 42.348  -> 46.521 ± 0.386 ns/op
  two_ordinals 83.531 ± 23.473  ->  8.617 ± 0.105 ns/op
```
The speed up is much better when the fields are ordinals because hashing
bytes is comparatively slow.

I believe the ordinals case is quite common. I've run into it in quite a
few profiles.

* ESQL: Test partially filtered aggs (#114510)

assertions.

* Introduce CRUD APIs for data stream options (#113945)

In this PR we introduce two endpoint PUT and GET to manage the data
stream options and consequently the failure store configuration on the
data stream level. This means that we can manage the failure store of
existing data streams.

The APIs look like:

```
# Enable/disable 
PUT _data_stream/my-data-stream/_options
{
  "failure_store": {
    "enabled": true
  }
}

# Remove existing configuration
DELETE _data_stream/my-data-stream/_options

# Retrieve 
GET _data_stream/my-data-stream/_options
{
  "failure_store": {
    "enabled": true
  }
}
```

Future work:

- Document the new APIs
- Convert `DataStreamOptionsIT.java` to a yaml test.

* Add ResolvedExpression wrapper (#114592)

**Introduction**

> In order to make adoption of failure stores simpler for all users, we
are introducing a new syntactical feature to index expression
resolution: The selector. > > Selectors, denoted with a :: followed by a
recognized suffix will allow users to specify which component of an
index abstraction they would like to operate on within an API call. In
this case, an index abstraction is a concrete index, data stream, or
alias; Any abstraction that can be resolved to a set of indices/shards.
We define a component of an index abstraction to be some searchable unit
of the index abstraction. > > To start, we will support two components:
data and failures. Concrete indices are their own data components, while
the data component for index aliases are all of the indices contained
therein. For data streams, the data component corresponds to their
backing indices. Data stream aliases mirror this, treating all backing
indices of the data streams they correspond to as their data component.
>  > The failure component is only supported by data streams and data
stream aliases. The failure component of these abstractions refer to the
data streams' failure stores. Indices and index aliases do not have a
failure component.

For more details and examples see
https://github.com/elastic/elasticsearch/pull/113144. All this work has
been cherry picked from there.

**Purpose of this PR**

This PR is introducing a wrapper around the resolved expression that
used to be a `String` to create the base on which the selectors are
going to be added.

The current PR is just a refactoring and does not and should not change
any existing behaviour.

* Update IndexSettingProvider#getAdditionalIndexSettings() signature (#114150)

With logsdb another index mode is available, the isTimeSeries parameter is limiting. Instead, we should just push down the index mode from template to index settings provider.

* [ML] Switch default chunking strategy to sentence (#114453)

* Don't close/recreate adaptive allocations metrics (#114721)

* Simplify `XContent` output of epoch times (#114491)

Today the overloads of `XContentBuilder#timeField` do two rather
different things: one formats an object as a `String` representation of
a time (where the object is either an unambiguous time object or else a
`long`) and the other formats only a `long` as one or two fields
depending on the `?human` flag.

This is trappy in a number of ways:

- `long` means an absolute (epoch) time, but sometimes folks will
  mistakenly use this for time intervals too.

- `long` means only milliseconds, there is no facility to specify a
  different unit.

- the dependence on the `?human` flag in exactly one of the overloads is
  kinda weird.

This commit removes the confusion by dropping support for considering a
`Long` as a valid representation of a time at all, and instead requiring
callers to either convert it into a proper time object or else call a
method that is explicitly expecting an epoch time in milliseconds.

* Clarify use of special values for publish addresses (#114551)

Special values like `0.0.0.0` may resolve to multiple IP addresses just
like hostnames, so the same considerations apply when using such values
as a publish address. This commit spells this case out in the docs and
cleans up the nearby wording a little.

* Test StDistance multivalue consistency and fixed two CartesianPoint bugs (#114729)

* Fix Synthetic Source Handling for `bit` Type in `dense_vector` Field (#114407)

**Description:**

This PR addresses the issue described in [#114402](https://github.com/elastic/elasticsearch/issues/114402), where the `synthetic_source` feature does not correctly handle the `bit` type in `dense_vector` fields when `index` is set to `false`. The root cause of the issue was that the `bit` type was not properly accounted for, leading to an array that is 8 times the size of the actual `dims` value of docvalue. This mismatch will causes an array out-of-bounds exception when reconstructing the document.

**Changes:**

- Adjusted the `synthetic_source` logic to correctly handle the `bit` type by ensuring the array size accounts for the 8x difference in dimensions.
- Added yaml test to cover the `bit` type scenario in `dense_vector` fields with `index` set to `false`.

**Related Issues:**

- Closes [#114402](https://github.com/elastic/elasticsearch/issues/114402)

* [ML] Stream Google Completion (#114596)

Google supports SSE for chat completion and sends the same payload as
their non-streaming calls, so we can reuse the SSE parser with our
existing parse function.

The downside is, google requires a different URI, so we refactored away
from the visitor pattern to allow for a different URI creating and set
during request time rather than on model instantiation time.

- Create a StreamingChatProcessor that subscribes to streaming results
  from bedrock and handles the parsing on another thread.
- There was no good way (that I could see) to extend the Provider-based
  CompletionRequestEntity, so they have been flattened into one
  RequestEntity that can be shared between ConverseRequest and
  ConverseStreamRequest.

 client_err = COUNT(*) WHERE 400 <= code AND code < 500,
 server_err = COUNT(*) WHERE 500 <= code AND code < 600,
 total_count = COUNT(*)

Implementation wise, the base AggregateFunction has been extended to
 allow a filter to be passed on. This is required to incorporate the
 filter as part of the aggregate equality/identify which would fail with
 the filter as an external component.

As part of the process, the serialization for the existing aggregations
 had to be fixed so AggregateFunction implementations so that it
 delegates to their parent first.

* Support multi-valued fields in compute engine for ST_DISTANCE (#114836)

In #112063 we added support for multivalued fields to the compute engine for ST_INTERSECTS and relatives, but not for ST_DISTANCE. In #114729 it was discovered that, at least for the common case of a field and a constant, this support was not needed due to ST_DISTANCE being re-written to ST_INTERSECTS. However, for many other cases, like ST_DISTANCE used on the coordinator node, or between two fields, this lack of support would result in null values.

This PR fixes those cases, making sure ST_DISTANCE uses the Block-Builder approach similar to what was done for ST_INTERSECTS et al.

A large number (almost the entirety) of tests in the `MlJobIT` tests suite have been muted. In all cases the cause of failure of the tests is the same, persistent tasks for `cluster:admin/xpack/ml/job/close` and `cluster:admin/xpack/ml/job/close[n]` have been detected as present after the test case has completed.

Examination of the tests show that the majority of them do not call either `close` directly or indirectly, indicating that the root cause lies with some previous test. As the `close` task inherits the default timeout of half an hour, an instance of it lingering about can cause a lot of damage to subsequent tests.

The approach taken in this PR is to call the `_task/_cancel` endpoint after every test execution in the `MlJobIT` suite as the final operation. This should restrict the impact of the lingering `close` task to the test responsible, and the reduction in noise should permit better identification of the culprit.

* Remove dead branches for v7 REST API (#114850)

In v9 the `getRestApiVersion()` method on `RestRequest`,
`XContentBuilder` and `XContentParser` can never return `V_7`, so we can
replace all the expressions of the form `$x$.getRestApiVersion() == V_7`
with `false`. This commit does that, and then refactors away the
resulting dead code using (largely) automated transformations.

* Retry `S3BlobContainer#getRegister` on all exceptions (#114813)

S3 register reads are subject to the regular client retry policy, but in
practice we see failures of these reads sometimes for errors that are
transient but for which the SDK does not retry. This commit adds another
layer of retries to these reads.

* [Failure store - selector syntax] Replace failureOptions with selector options internally. (#114812)

**Introduction**

> In order to make adoption of failure stores simpler for all users, we
are introducing a new syntactical feature to index expression
resolution: The selector. > > Selectors, denoted with a :: followed by a
recognized suffix will allow users to specify which component of an
index abstraction they would like to operate on within an API call. In
this case, an index abstraction is a concrete index, data stream, or
alias; Any abstraction that can be resolved to a set of indices/shards.
We define a component of an index abstraction to be some searchable unit
of the index abstraction. > > To start, we will support two components:
data and failures. Concrete indices are their own data components, while
the data component for index aliases are all of the indices contained
therein. For data streams, the data component corresponds to their
backing indices. Data stream aliases mirror this, treating all backing
indices of the data streams they correspond to as their data component.
>  > The failure component is only supported by data streams and data
stream aliases. The failure component of these abstractions refer to the
data streams' failure stores. Indices and index aliases do not have a
failure component.

For more details and examples see
https://github.com/elastic/elasticsearch/pull/113144. All this work has
been cherry picked from there.

**Purpose of this PR**

This PR is replacing the `FailureStoreOptions` with the
`SelectorOptions`, there shouldn't be any perceivable change to the user
since we kept the query parameter "failure_store" for now. It will be
removed in the next PR which will introduce the parsing of the
expressions. 

_The current PR is just a refactoring and does not and should not change
any existing behaviour._

* Inject the `host.name` field mapping only if required for `logsdb` index mode (#114573)

Here we check for the existence of a `host.name` field in index sort settings
when the index mode is `logsdb` and decide to inject the field in the mapping
depending on whether it exists or not. By default `host.name` is required for
sorting in LogsDB. This reduces the chances for errors at mapping or template
composition time as a result of injecting the `host.name` field only if strictly
required. A user who wants to override index sort settings without including
a `host.name` field would be able to do so without finding an addi…
