The cat nodes API performs a `ClusterStateAction` then a `NodesInfoAction`.
Today it accepts the `?local` parameter and passes this to the
`ClusterStateAction` but this parameter has no effect on the `NodesInfoAction`.
This is surprising, because `GET _cat/nodes?local` looks like it might be a
completely local call but in fact it still depends on every node in the
cluster.
This commit deprecates the `?local` parameter on this API so that it can be
removed in 8.0.

testCancelRecoveryDuringPhase1 uses a mock of IndexShard, which can't

The additional change to the original PR (#49657), is that `org.elasticsearch.client.cluster.RemoteConnectionInfo` now parses the initial_connect_timeout field as a string instead of a TimeValue instance.
The reason that this is needed is because that the initial_connect_timeout field in the remote connection api is serialized for human consumption, but not for parsing purposes.
Therefore the HLRC can't parse it correctly (which caused test failures in CI, but not in the PR CI
:( ). The way this field is serialized needs to be changed in the remote connection api, but that is a breaking change. We should wait making this change until rest api versioning is introduced.

Today, the replica allocator uses peer recovery retention leases to
select the best-matched copies when allocating replicas of indices with
soft-deletes. We can employ this mechanism for indices without
soft-deletes because the retaining sequence number of a PRRL is the
persisted global checkpoint (plus one) of that copy. If the primary and
replica have the same retaining sequence number, then we should be able
to perform a noop recovery. The reason is that we must be retaining
translog up to the local checkpoint of the safe commit, which is at most
the global checkpoint of either copy). The only limitation is that we
might not cancel ongoing file-based recoveries with PRRLs for noop
recoveries. We can't make the translog retention policy comply with
PRRLs. We also have this problem with soft-deletes if a PRRL is about to
expire.

Both geo_bounding_box query and geo_bounds aggregation have
a very similar definition of a "bounding box". A lot of this
logic (serialization, xcontent-parsing, etc) can be centralized
instead of having separated efforts to do the same things
This commit makes the TransportRolloverAction more resilient, by having it execute
only one cluster state update that creates the new (rollover index), rolls over
the alias from the source to the target index and set the RolloverInfo on the
source index. Before these 3 steps were represented as 3 chained cluster state
updates, which would've seen the user manually intervene if, say, the alias
rollover cluster state update (second in the chain) failed but the creation of
the rollover index (first in the chain) update succeeded

This is a spinoff of #48130 that generalizes the proposal to allow early termination with the composite aggregation when leading sources match a prefix or the entire index sort specification.
In such case the composite aggregation can use the index sort natural order to early terminate the collection when it reaches a composite key that is greater than the bottom of the queue.
The optimization is also applicable when a query other than match_all is provided. However the optimization is deactivated for sources that match the index sort in the following cases:
* Multi-valued source, in such case early termination is not possible.
* missing_bucket is set to true
Follow-up to #48974 that ensures that replicas are only auto-expanded according to allocation
filtering rules once all nodes are upgraded to a version that supports this. Helps with
orchestrating cluster upgrades.
refactors source and dest validation, adds support for CCS, makes resolve work like reindex/search, allow aliased dest index with a single write index.

The built-in task index mapping has a version field in its metadata, so that
the TaskResultsService can check to see if it needs to update mappings when
a new task result is stored. #48393 updated this version in TaskResultsService
but omitted to change the version in the mapping itself, so a mapping update
is applied every time a new task result is stored.
This commit updates the mapping version so that it corresponds to the version
in TaskResultsService.

* Update remote cluster stats to support simple mode (#49961)
Remote cluster stats API currently only returns useful information if
the strategy in use is the SNIFF mode. This PR modifies the API to
provide relevant information if the user is in the SIMPLE mode. This
information is the configured addresses, max socket connections, and
open socket connections.
* Send hostname in SNI header in simple remote mode (#50247)
Currently an intermediate proxy must route conncctions to the
appropriate remote cluster when using simple mode. This commit offers
a additional mechanism for the proxy to route the connections by
including the hostname in the TLS SNI header.
* Rename the remote connection mode simple to proxy (#50291)
This commit renames the simple connection mode to the proxy connection
mode for remote cluster connections. In order to do this, the mode specific
settings which we namespaced by their mode (ex: sniff.seed and
proxy.addresses) have been reverted.
* Modify proxy mode to support a single address (#50391)
Currently, the remote proxy connection mode uses a list setting for the
proxy address. This commit modifies this so that the setting is
proxy_address and only supports a single remote proxy address.
Avoid backwards incompatible changes for 8.x and 7.6 by removing type
restriction on compile and Factory. Factories may optionally implement
ScriptFactory. If so, then they can indicate determinism and thus
cacheability.

We randomly generate intervals sources to test serialization and query generation
in IntervalQueryBuilderTests. However, rarely we can generate a query that has
too many nested disjunctions, resulting in query rewrites running afoul of the maximum
boolean clause limit.
This commit reduces the maximum depth of the randomly generated intervals source
to make running into this limit much more unlikely.
* Extract IndexCreationTask execute into applyCreateIndexRequest
This is the first step in preparation for separating the index creation into a few
steps that only deal with the cluster state mutation and removing the IndexCreationTask
altogether.
* Split applyCreateIndexRequest
This breaks down the logic in applyCreateIndexRequest into multiple
steps that will hopefully make the service more readable and unit testable.
The service creation process now goes through a few well defined steps,
namely find the templates that possibly match the new index, parse the
requested and template matching mappings, process the index and template
matching settings, validate the wait for active shards request and
create the `IndexService`, update the mappings in the `MapperService` (which
is grouped together with creating the sort order for validation purposes),
validate the requested and templated matching aliases and finally update
the `ClusterState` to reflect the requested changes.
This also removes the `IndexCreationTask` as it was a shallow
indirection and migrates the tests from `IndexCreationTaskTests` to
`MetaDataCreateIndexServiceTests` (making them "real" unit tests
operating on the `ClusterState` rather than mocks).
* Add more unit tests.
* Add IT to verify we cleanup in case of failure

Loading shard state information during shard allocation sometimes runs into a situation where a
data node does not know yet how to look up the shard on disk if custom data paths are used.
The current implementation loads the index metadata from disk to determine what the custom
data path looks like. This PR removes this dependency, simplifying the lookup.

We can simply filter out shard generation updates for indices
that were removed from the cluster state concurrently to fix
index deletes during partial snapshots as that completely removes
any reference to those shards from the snapshot.

This change removes falling back to listing out the repository contents to find the latest `index-N` in write-mounted blob store repositories.
This saves 2-3 list operations on each snapshot create and delete operation. Also it makes all the snapshot status APIs cheaper (and faster) by saving one list operation there as well in many cases.
This removes the resiliency to concurrent modifications of the repository as a result and puts a repository in a `corrupted` state in case loading `RepositoryData` failed from the assumed generation.
G1GC will use humongous allocations when an allocation exceeds half the
chosen region size, which is minimum 1MB. By reducing the recovery
buffer size by 16 bytes we ensure that the recovery buffer is never
allocated as a humongous allocation.
Today we do not consider trimAboveSeqNo when calculating the translog
generation of an index commit. If there is no new indexing after the
primary promotion, then we won't be able to clean up the translog.

The current Docker entrypoint script picks up environment variables and
translates them into -E command line arguments. However, since any tool
executes via `docker exec` doesn't run the entrypoint, it results in
a poorer user experience.
Therefore, refactor the env var handling so that the -E options are
generated in `elasticsearch-env`. These have to be appended to any
existing command arguments, since some CLI tools have subcommands and
-E arguments must come after the subcommand.
Also extract the support for `_FILE` env vars into a separate script, so
that it can be called from more than once place (the behaviour is
idempotent).
Finally, add noop -E handling to CronEvalTool for parity, and support
`-E` in MultiCommand before subcommands.
With #45689 making it so that index metadata is written
after all shards have been snapshotted we can't delete indices
that are part of the upcoming snapshot finalization any longer
and it is not sufficient to check if all shards of an index have been
snapshotted before deciding that it is safe to delete it.
This change forbids deleting any index that is in the process of being
snapshot to avoid issues during snapshot finalization.

* Remove BlobContainer Tests against Mocks
Removing all these weird mocks as asked for by #30424.
All these tests are now part of real repository ITs and otherwise left unchanged if they had
independent tests that didn't call the `createBlobStore` method previously.
The HDFS tests also get added coverage as a side-effect because they did not have an implementation
of the abstract repository ITs.

Lucene 8.4 added support for "CONTAINS", therefore in this commit those
changes are integrated in Elasticsearch. This commit contains as well a
bug fix when querying with a geometry collection with "DISJOINT" relation.
Since 7.4, we switch from translog to Lucene as the source of history
for peer recoveries. However, we reduce the likelihood of
operation-based recoveries when performing a full cluster restart from
pre-7.4 because existing copies do not have PPRL.
To remedy this issue, we fallback using translog in peer recoveries if
the recovering replica does not have a peer recovery retention lease,
and the replication group hasn't fully migrated to PRRL.
Relates #45136
Today we do not use retention leases in peer recovery for closed indices
because we can't sync retention leases on closed indices. This change

When decoupling the pipeline reduction from regular agg reduction,
MultiBucket aggs were modified to reduce their bucket's pipeline
aggs first before reducing the sibling aggs. This modification
was missed on SingleBucket aggs, meaning any SingleBucket would
fail to reduce any pipeline sub-aggs
* Remove Unused Single Delete in BlobStoreRepository
There are no more production uses of the non-bulk delete or the delete that throws
on missing so this commit removes both these methods.
Only the bulk delete logic remains. Where the bulk delete was derived from single deletes,
the single delete code was inlined into the bulk delete method.
Where single delete was used in tests it was replaced by bulk deleting.
* Better Logging GCS Blobstore Mock
Two things:
1. We should just throw a descriptive assertion error and figure out why we're not reading a multi-part instead of
returning a `400` and failing the tests that way here since we can't reproduce these 400s locally.
2. We were missing logging the exception on a cleanup delete failure that coincides with the `400` issue in tests.
