this commit adds aggregation support for the geo_shape field
type on geo*_grid aggregations.
it introduces a Tiler for both tiles and hashes that enables a new type of
ValuesSource to replace the GeoPoint's CellIdSource. This makes it possible
for the existing Aggregator to be re-used, so no new implementations of
the grid aggregators are added.
The following settings are now no-ops:
* xpack.flattened.enabled
* xpack.logstash.enabled
* xpack.rollup.enabled
* xpack.slm.enabled
* xpack.sql.enabled
* xpack.transform.enabled
* xpack.vectors.enabled
Since these settings no longer need to be checked, we can remove settings
parameters from a number of constructors and methods, and do so in this
commit.
We also update documentation to remove references to these settings.
This PR implements the following changes to make ML model snapshot
retention more flexible in advance of adding a UI for the feature in
an upcoming release.
- The default for `model_snapshot_retention_days` for new jobs is now
10 instead of 1
- There is a new job setting, `daily_model_snapshot_retention_after_days`,
that defaults to 1 for new jobs and `model_snapshot_retention_days`
for pre-7.8 jobs
- For days that are older than `model_snapshot_retention_days`, all
model snapshots are deleted as before
- For days that are in between `daily_model_snapshot_retention_after_days`
and `model_snapshot_retention_days` all but the first model snapshot
for that day are deleted
- The `retain` setting of model snapshots is still respected to allow
selected model snapshots to be retained indefinitely

As of elastic/ml-cpp#1179, the analytics process reports phases
depending on the analysis type. This commit adjusts the phases
of current analyses from `analyzing` to the following:
- outlier_detection: [`computing_outlier`]
- regression/classification: [`feature_selection`, `coarse_parameter_search`, `fine_tuning_parameters`, `final_training`]

Move includeDataStream flag from an IndicesOptions to IndexNameExpressionResolver.Context
as a dedicated field that callers to IndexNameExpressionResolver can set.
Also alter indices stats api to support data streams.
The rollover api uses this api and otherwise rolling over data stream does no longer work.

Backport of #55858 to 7.x branch.
Currently the TransportBulkAction detects whether an index is missing and
then decides whether it should be auto created. The coordination of the
index creation also happens in the TransportBulkAction on the coordinating node.
This change adds a new transport action that the TransportBulkAction delegates to
if missing indices need to be created. The reasons for this change:
* Auto creation of data streams can't occur on the coordinating node.
Based on the index template (v2) either a regular index or a data stream should be created.
However if the coordinating node is slow in processing cluster state updates then it may be
unaware of the existence of certain index templates, which then can load to the
TransportBulkAction creating an index instead of a data stream. Therefor the coordination of
creating an index or data stream should occur on the master node. See #55377
* From a security perspective it is useful to know whether index creation originates from the
create index api or from auto creating a new index via the bulk or index api. For example
a user would be allowed to auto create an index, but not to use the create index api. The
auto create action will allow security to distinguish these two different patterns of
index creation.
This change adds the following new transport actions:
AutoCreateAction, the TransportBulkAction redirects to this action and this action will actually create the index (instead of the TransportCreateIndexAction). Later via #55377, can improve the AutoCreateAction to also determine whether an index or data stream should be created.
The create_index index privilege is also modified, so that if this permission is granted then a user is also allowed to auto create indices. This change does not yet add an auto_create index privilege. A future change can introduce this new index privilege or modify an existing index / write index privilege.

* Allow Deleting Multiple Snapshots at Once (#55474)
Adds deleting multiple snapshots in one go without significantly changing the mechanics of snapshot deletes otherwise.
This change does not yet allow mixing snapshot delete and abort. Abort is still only allowed for a single snapshot delete by exact name.
* Make xpack.monitoring.enabled setting a no-op
This commit turns xpack.monitoring.enabled into a no-op. Mostly, this involved
removing the setting from the setup for integration tests. Monitoring may
introduce some complexity for test setup and teardown, so we should keep an eye
out for turbulence and failures
* Docs for making deprecated setting a no-op
This commit converts the remaining isXXXAllowed methods to instead of
use isAllowed with a Feature value. There are a couple other methods
that are static, as well as some licensed features that check the
license directly, but those will be dealt with in other followups.
* Make xpack.ilm.enabled setting a no-op
* Add watcher setting to not use ILM
* Update documentation for no-op setting
* Remove NO_ILM ml index templates
* Remove unneeded setting from test setup
* Inline variable definitions for ML templates
* Use identical parameter names in templates
* New ILM/watcher setting falls back to old setting
* Add fallback unit test for watcher/ilm setting
implement throttling in async-indexer used by rollup and transform. The added
docs_per_second parameter is used to calculate a delay before the next
search request is send. With re-throttle its possible to change the parameter
at runtime. When stopping a running job, its ensured that despite throttling
the indexer stops in reasonable time. This change contains the groundwork, but
does not expose the new functionality.

We were creating PemKeyConfig objects using different private
keys but always using testnode.crt certificate that uses the
RSA public key. The PemKeyConfig was built but we would
then later fail to handle SSL connections during the TLS
handshake eitherway.
This became obvious in FIPS tests where the consistency
checks that FIPS 140 mandates kick in and failed early
becausethe private key was of different type than the
public key
Anonymous roles resolution and user role deduplication are now performed during authentication instead of authorization. The change ensures:
* If anonymous access is enabled, user will be able to see the anonymous roles added in the roles field in the /_security/_authenticate response.
* Any duplication in user roles are removed and will not show in the above authenticate response.
* In any other case, the response is unchanged.
It also introduces a behaviour change: the anonymous role resolution is now authentication node specific, previously it was authorization node specific. Details can be found at #47195 (comment)
This change adds a new setting, daily_model_snapshot_retention_after_days,
to the anomaly detection job config.
Initially this has no effect, the effect will be added in a followup PR.
This PR gets the complexities of making changes that interact with BWC
over well before feature freeze.

This is a continuation from #55580.
Now that we're parsing phase progresses from the analytics process
we change `ProgressTracker` to allow for custom phases between
the `loading_data` and `writing_results` phases. Each `DataFrameAnalysis`
may declare its own phases.
This commit sets things in place for the analytics process to start
reporting different phases per analysis type. However, this is
still preserving existing behaviour as all analyses currently
declare a single `analyzing` phase.

License state is currently made up of boolean methods that check whether
a particular feature is allowed by the current license state. Each new
feature must copy/past boiler plate code. While that has gotten easier
with utilities like isAllowedByLicense, this is still more cumbersome
than should be necessary. This commit adds a general purpose isAllowed
method which takes a new Feature enum, where each value of the enum
defines the minimum license mode and whether the license must be active
to be allowed. Only security features are converted in this PR, in order
to keep the commit size relatively small. The rest of the features will
be converted in a followup.
The (de)serialization code of the async search response
cannot handle exceptions that extend ElasticsearchException (e.g. ScriptException).
This commit fixes this bug by serializing the error with the more generic
StreamInput#writeException.
EQL will require very similar functionality to async search. This PR refactors
AsyncSearchIndexService to make it reusable for EQL.

Out of the box "access granted" audit events are not logged
for system users. The list of system users was stale and included
only the _system and _xpack users. This commit expands this list
with _xpack_security and _async_search, effectively reducing the
auditing noise by not logging the audit events of these system
users out of the box.

Instead of doing our own checks against REST status, shard counts, and shard failures, this commit changes all our extractor search requests to set `.setAllowPartialSearchResults(false)`.

Adds a "node" field to the response from the following endpoints:
1. Open anomaly detection job
2. Start datafeed
3. Start data frame analytics job
If the job or datafeed is assigned to a node immediately then
this field will return the ID of that node.
In the case where a job or datafeed is opened or started lazily
the node field will contain an empty string. Clients that want
to test whether a job or datafeed was opened or started lazily
can therefore check for this.

PEMUtils would incorrectly fill the encryption password with zeros
(the '\0' character) after decrypting a PKCS#8 key.
Since PEMUtils did not take ownership of this password it should not
zero it out because it does not know whether the caller will use that
password array again. This is actually what PEMKeyConfig does - it
uses the key encryption password as the password for the ephemeral
keystore that it creates in order to build a KeyManager.

This change folds the removal of the in-progress snapshot entry
into setting the safe repository generation. Outside of removing
an unnecessary cluster state update, this also has the advantage
of removing a somewhat inconsistent cluster state where the safe
repository generation points at `RepositoryData` that contains a
finished snapshot while it is still in-progress in the cluster
state, making it easier to reason about the state machine of
upcoming concurrent snapshot operations.
Today a read-only engine requires a complete history of operations, in the
sense that its local checkpoint must equal its maximum sequence number. This is
a valid check for read-only engines that were obtained by closing an index
since closing an index waits for all in-flight operations to complete. However
a snapshot may not have this property if it was taken while indexing was
ongoing, but that's ok.
This commit weakens the check for a complete history to exclude the case of a
searchable snapshot.

This change ensures that we return the latest expiration time
when retrieving the response from the index.
This commit also fixes a bug that stops the garbage collection of saved responses if the async search index is deleted.
`updateAndGet` could actually call the internal method more than once on contention.
If I read the JavaDocs, it says:
```* @param updateFunction a side-effect-free function```
So, it could be getting multiple updates on contention, thus having a race condition where stats are double counted.
To fix, I am going to use a `ReadWriteLock`. The `LongAdder` objects allows fast thread safe writes in high contention environments. These can be protected by the `ReadWriteLock::readLock`.
When stats are persisted, I need to call reset on all these adders. This is NOT thread safe if additions are taking place concurrently. So, I am going to protect with `ReadWriteLock::writeLock`.
This should prevent race conditions while allowing high (ish) throughput in the highly contention paths in inference.
I did some simple throughput tests and this change is not significantly slower and is simpler to grok (IMO).

This validation is not needed, as we have discovered the source of the
serialization error that was leading to some usage instances appearing
to not have a name.
This change reworks the loading and monitoring of files that are used
for the construction of SSLContexts so that updates to these files are
not lost if the updates occur during startup. Previously, the
SSLService would parse the settings, build the SSLConfiguration
objects, and construct the SSLContexts prior to the
SSLConfigurationReloader starting to monitor these files for changes.
This allowed for a small window where updates to these files may never
be observed until the node restarted.
To remove the potential miss of a change to these files, the code now
parses the settings and builds SSLConfiguration instances prior to the
construction of the SSLService. The files back the SSLConfiguration
instances are then registered for monitoring and finally the SSLService
is constructed from the previously parse SSLConfiguration instances. As
the SSLService is not constructed when the code starts monitoring the
files for changes, a CompleteableFuture is used to obtain a reference
to the SSLService; this allows for construction of the SSLService to
complete and ensures that we do not miss any file updates during the
construction of the SSLService.
While working on this change, the SSLConfigurationReloader was also
refactored to reflect how it is currently used. When the
SSLConfigurationReloader was originally written the files that it
monitored could change during runtime. This is no longer the case as
we stopped the monitoring of files that back dynamic SSLContext
instances. In order to support the ability for items to change during
runtime, the class made use of concurrent data structures. The use of
these concurrent datastructures has been removed.

Security features in the license state currently do a dynamic check on
whether security is enabled. This is because the license level can
change the default security enabled state. This commit splits out the
check on security being enabled, so that the combo method of security
enabled plus license allowed is no longer necessary.
