The client-side encrypted repository is a new type of snapshot repository that
internally delegates to the regular variants of snapshot repositories (of types
Azure, S3, GCS, FS, and maybe others but not yet tested). After the encrypted
repository is set up, it is transparent to the snapshot and restore APIs (i.e. all
snapshots stored in the encrypted repository are encrypted, no other parameters
required).
The encrypted repository is protected by a password stored on every node's
keystore (which must be the same across the nodes).
The password is used to generate a key encrytion key (KEK), using the PBKDF2
function, which is used to encrypt (using the AES Wrap algorithm) other
symmetric keys (referred to as DEK - data encryption keys), which themselves
are generated randomly, and which are ultimately used to encrypt the snapshot
blobs.
For example, here is how to set up an encrypted FS repository:
------
1) make sure that the cluster runs under at least a "platinum" license
(simplest test configuration is to put `xpack.license.self_generated.type: "trial"`
in the elasticsearch.yml file)
2) identical to the un-encrypted FS repository, specify the mount point of the
shared FS in the elasticsearch.yml conf file (on all the cluster nodes),
e.g. `path.repo: ["/tmp/repo"]`
3) store the repository password inside the elasticsearch.keystore, *on every cluster node*.
In order to support changing password on existing repository (implemented in a follow-up),
the password itself must be names, e.g. for the "test_enc_key" repository password name:
`./bin/elasticsearch-keystore add repository.encrypted.test_enc_pass.password`
*type in the password*
4) start up the cluster and create the new encrypted FS repository, named "test_enc", by calling:
`
curl -X PUT "localhost:9200/_snapshot/test_enc?pretty" -H 'Content-Type: application/json' -d'
{
"type": "encrypted",
"settings": {
"location": "/tmp/repo/enc",
"delegate_type": "fs",
"password_name": "test_enc_pass"
}
}
'
`
5) the snapshot and restore APIs work unmodified when they refer to this new repository, e.g.
` curl -X PUT "localhost:9200/_snapshot/test_enc/snapshot_1?wait_for_completion=true"`

Encrypted snapshots are available on active PLATINUM and ENTERPRISE license modes.
Listing encrypted repositories, as well as restoring and deleting encrypted snapshots is still
permitted after the license expires or is downgraded, to avoid a data hostage situation.
This PR updates the last usage time stamp of the encrypted snapshots feature to the creation
time of the most recent encrypted snapshot.
