This adds a frozen phase to ILM that will allow the execution of the
set_priority, unfollow, allocate, freeze and searchable_snapshot actions.
The frozen phase will be executed after the cold and before the delete phase.

* Fix merge issues
* use former 7.x common test configuration
This change fixes two possible race conditions in SLM related to
how local master changes and cluster state events are observed. When
implementing the `LocalNodeMasterListener` interface, it is only
recommended to execute on a separate threadpool if the operations are
heavy and would block the cluster state thread. SLM specified that the
listeners should run in the Snapshot thread pool, but the operations
in the listener were lightweight. This had the side effect of causing
master changes to be delayed if the Snapshot threads were all busy and
could also potentially cause the `onMaster` and `offMaster` calls to
race if both were queued and then executed concurrently. Additionally,
the `SnapshotLifecycleService` is also a `ClusterStateListener` and
there is currently no order of operations guarantee between
`LocalNodeMasterListeners` and `ClusterStateListeners` so this could
lead to incorrect behavior.
The resolution for these two issues is that the
SnapshotRetentionService now specifies the `SAME` executor for its
implementation of the `LocalNodeMasterListener` interface. The
`SnapshotLifecycleService` is no longer a `LocalNodeMasterListener` and
instead tracks local master changes in its `ClusterStateListner`.
Backport of #59801
The ILM policy for the source and shrunk indices run separately (ie. they
are two separate managed indices). This fixes the test which exhibited some
flakiness by allowing some time for the ILM policy for the source index
to finish executing.

Restoring a data stream from a snapshot could install a data stream that
doesn't match any composable templates. This also makes the `template`

This commit creates a new Gradle plugin to provide a separate task name
and source set for running YAML based REST tests. The only project
converted to use the new plugin in this PR is distribution/archives/integ-test-zip.
For which the testing has been moved to :rest-api-spec since it makes the most
sense and it avoids a small but awkward change to the distribution plugin.
The remaining cases in modules, plugins, and x-pack will be handled in followups.
This plugin is distinctly different from the plugin introduced in #55896 since
the YAML REST tests are intended to be black box tests over HTTP. As such they
should not (by default) have access to the classpath for that which they are testing.
The YAML based REST tests will be moved to separate source sets (yamlRestTest).
The which source is the target for the test resources is dependent on if this
new plugin is applied. If it is not applied, it will default to the test source
set.
Further, this introduces a breaking change for plugin developers that
use the YAML testing framework. They will now need to either use the new source set
and matching task, or configure the rest resources to use the old "test" source set that
matches the old integTest task. (The former should be preferred).
As part of this change (which is also breaking for plugin developers) the
rest resources plugin has been removed from the build plugin and now requires
either explicit application or application via the new YAML REST test plugin.
Plugin developers should be able to fix the breaking changes to the YAML tests
by adding apply plugin: 'elasticsearch.yaml-rest-test' and moving the YAML tests
under a yamlRestTest folder (instead of test)
Backport of #58582 to 7.x branch.
This commit adds a new metadata field mapper that validates,
that a document has exactly a single timestamp value in the data stream timestamp field and
that the timestamp field mapping only has `type`, `meta` or `format` attributes configured.
Other attributes can affect the guarantee that an index with this meta field mapper has a
useable timestamp field.
The MetadataCreateIndexService inserts a data stream timestamp field mapper whenever
a new backing index of a data stream is created.

We don't allow converting a data stream's writeable index into a searchable
snapshot. We are currently preventing swapping a data stream's write index
with the restored index.
This adds another step that will not proceed with the searchable snapshot action
until the managed index is not the write index of a data stream anymore.

The shrink action creates a shrunken index with the target number of shards.
This makes the shrink action data stream aware. If the ILM managed index is
part of a data stream the shrink action will make sure to swap the original
managed index with the shrunken one as part of the data stream's backing
indices and then delete the original index.

As the datastream information is stored in the `ClusterState.Metadata` we exposed
the `Metadata` to the `AsyncWaitStep#evaluateCondition` method in order for
the steps to be able to identify when a managed index is part of a DataStream.
If a managed index is part of a DataStream the rollover target is the DataStream
name and the highest generation index is the write index (ie. the rolled index).

We believe there's no longer a need to be able to disable basic-license
features completely using the "xpack.*.enabled" settings. If users don't
want to use those features, they simply don't need to use them. Having
such features always available lets us build more complex features that
assume basic-license features are present.
This commit deprecates settings of the form "xpack.*.enabled" for
basic-license features, excluding "security", which is a special case.
It also removes deprecated settings from integration tests and unit
tests where they're not directly relevant; e.g. monitoring and ILM are
no longer disabled in many integration tests.
Asserting on the failed_step field from the explainAPI can produce flakiness
because the ILM state is moved back and forth between the (failing) step and
the ERROR step (as the workflow is retry, fail then move to ERROR step,
move back to the (failing) step, retry, fail, etc) and the failed_step
information is only available whilst in the ERROR state.
Unmute other tests as they were collateral failures
A read-only index could not be deleted in the wipeCluster phase and caused
these failures

This is a simple naming change PR, to fix the fact that "metadata" is a
single English word, and for too long we have not followed general
naming conventions for it. We are also not consistent about it, for
example, METADATA instead of META_DATA if we were trying to be
consistent with MetaData (although METADATA is correct when considered
in the context of "metadata"). This was a simple find and replace across
the code base, only taking a few minutes to fix this naming issue
forever.

* Smarter copying of the rest specs and tests (#52114)
This PR addresses the unnecessary copying of the rest specs and allows
for better semantics for which specs and tests are copied. By default
the rest specs will get copied if the project applies
`elasticsearch.standalone-rest-test` or `esplugin` and the project
has rest tests or you configure the custom extension `restResources`.
This PR also removes the need for dozens of places where the x-pack
specs were copied by supporting copying of the x-pack rest specs too.
The plugin/task introduced here can also copy the rest tests to the
local project through a similar configuration.
The new plugin/task allows a user to minimize the surface area of
which rest specs are copied. Per project can be configured to include
only a subset of the specs (or tests). Configuring a project to only
copy the specs when actually needed should help with build cache hit
rates since we can better define what is actually in use.
However, project level optimizations for build cache hit rates are
not included with this PR.
Also, with this PR you can no longer use the includePackaged flag on
integTest task.
The following items are included in this PR:
* new plugin: `elasticsearch.rest-resources`
* new tasks: CopyRestApiTask and CopyRestTestsTask - performs the copy
* new extension 'restResources'
```
restResources {
restApi {
includeCore 'foo' , 'bar' //will include the core specs that start with foo and bar
includeXpack 'baz' //will include x-pack specs that start with baz
}
restTests {
includeCore 'foo', 'bar' //will include the core tests that start with foo and bar
includeXpack 'baz' //will include the x-pack tests that start with baz
}
}

We marked the `init` ILM step as retryable but our test used `waitUntil`
without an assert so we didn’t catch the fact that we were not actually
able to retry this step as our ILM state didn’t contain any information
about the policy execution (as we were in the process of initialising
it).
This commit manually sets the current step to `init` when we’re moving
the ilm policy into the ERROR step (this enables us to successfully
move to the error step and later retry the step)

* Allow forcemerge in the hot phase for ILM policies
This commit changes the `forcemerge` action to also be allowed in the `hot` phase for policies. The
forcemerge will occur after a rollover, and allows users to take advantage of higher disk speeds for
performing the force merge (on a separate node type, for example).
On caveat with this is that a `forcemerge` in the `hot` phase *MUST* be accompanied by a `rollover`
action. ILM validates policies to ensure this is the case.

* Make randomTimeseriesLifecyclePolicy single-pass

We suspect the flakiness could’ve come from the fact that the rollover
step used to create the new index and roll the write alias to the new
index in separate cluster state updates. So the assertion that the
rolled index exists could’ve passed in the test but, before the
alias was rolled over to the new index, the subsequent write we execute
in the test (namely
`indexDocs("test_user", "x-pack-test-password", "foo_alias", 1)`)
would’ve sent the new document to the source index (ie. foo-logs-000001)
This would see the source index containing 3 documents and the rolled
index (foo-logs-000002) 0 documents.
However, we fixed this and the rollover step executes the “create index
and roll alias” in one single cluster update, so this situation should
not occur anymore.
