I don't think this needs to be async

Yeah, we forgot to remove async when we removed the lzma compression this morning.

We should move this out into a common place because we'll need to use it in the UI too, I think

I think you could give the variable a type of TranslatedEntry
here and then you won't need to do as TranslatedEntry
below.

Summary
This PR manages the entire lifecycle of exception list artifacts which will be delivered to the Elastic Endpoint. Major features include:
A periodic task runner that
compresses them(compression TBD in next PR), and computes hashesA new Kibana endpoint for downloading the artifacts
Properties
Eventual Consistency from
lists
toingest_manager
The feature has been designed to run seamlessly in a multi-Kibana environment. The manifest SO that is committed is intended as a kind of "ack" to indicate that a manifest has been dispatched (written to ingest manager datasource). In the event of an unexpected server crash, it's possible that a manifest can be dispatched more than once, however it should never be possible for a manifest change to be lost.
There is one potential edge case... on the callback for datasource create, we're unable to verify that the change is actually committed at the ingest manager layer. A crash after we return could result in a manifest update being lost. Revisit this?
Consistency of the Artifact Manifest
The TaskManager plugin is leveraged for maintenance of the artifacts and the manifest commit records. This should ensure that only one task is running at once, however we do also have the ingestManager callback that runs when a datasource is created. In order to prevent race conditions and therefore consistency issues on the manifest, we utilize the
version
that is returned using the SavedObjectsClient APIs. If two clients attempt to make simultaneous updates against the same base version, a conflict (409) will be encountered, and the manifest will be updated on the next task run (within 60 seconds) if necessary.Scale Considerations
The artifact manifest is now sent to the endpoint via the config/policy mechanism. The manifest can only be updated every 60 seconds, with the exception of when a new datasource is created, which could result in an out-of-band manifest update.
Artifacts are saved using a pre-calculated document ID, which encapsulates the schema version, operating system, artifact identifier, and fingerprint (a sha256 hash). Though downloads are currently managed through a Kibana API, we try to make the lookup as quickly as possible by utilizing a direct
get
by ID, and by utilizing an in-memory FIFO cache per client.Testing
