Add SAML IdP plugin for internal use (#54046) (#54124)
This change merges the "feature-internal-idp" branch into Elasticsearch.

This introduces a small identity-provider plugin as a child of the x-pack module.
This allows ES to act as a SAML IdP, for users who are authenticated against the
Elasticsearch cluster.

This feature is intended for internal use within Elastic Cloud environments
and is not supported for any other use case. It falls under an enterprise license tier.

The IdP is disabled by default.

Add version guards around Transform hidden index settings (#54036)
This commit ensures that the hidden index settings are only applied to the
Transform index templates when the cluster can support those settings.

Also unmutes the tests which were failing due to the previous behavior.

EQL: Fix custom scripting for functions (#53935) (#54114)
Improve separation of scripting between EQL and SQL by delegating common
methods to QL. The context detection is determined based on the package
to avoid having repetitive class hierarchies.
The Painless whitelists have been improved so that the declaring class
is used instead of the inherited one.

EQL: Add Substring function with Python semantics (#53688)

Does not reuse substring from SQL due to the difference in semantics and
the accepted arguments.
Currently it is missing full integration tests as, due to the usage of
scripting, requires an actual integration test against a proper cluster
(and likely its own QA project).

Jim Ferenczi 0330bef409 Improve async search's tasks cancellation (#53799)
This commit adds an explicit cancellation of the search task if
the initial async search submit task is cancelled (connection closed by the user).
This was previously done through the cancellation of the parent task but we don't
handle grand-children cancellation yet so we have to manually cancel the search task
in order to ensure that shard actions are cancelled too.
This change can be considered as a workaround until #50990 is fixed.

[ML] Introduce a "starting" datafeed state for lazy jobs (#54065)
It is possible for ML jobs to open lazily if the "allow_lazy_open"
option in the job config is set to true.  Such jobs wait in the
"opening" state until a node has sufficient capacity to run them.

This commit fixes the bug that prevented datafeeds for jobs lazily
waiting assignment from being started.  The state of such datafeeds
is "starting", and they can be stopped by the stop datafeed API
while in this state with or without force.

[7.x][ML] Data frame analytics data counts (#53998) (#54031)
This commit instruments data frame analytics
with stats for the data that are being analyzed.
In particular, we count training docs, test docs,
and skipped docs.

In order to account docs with missing values as skipped
docs for analyses that do not support missing values,
this commit changes the extractor so that it only ignores
docs with missing values when it collects the data summary,
which is used to estimate memory usage.

[ML] adds multi-class feature importance support (#53803) (#54024)
Adds multi-class feature importance calculation. 

Feature importance objects are now mapped as follows
(logistic) Regression:
```
{
   "feature_name": "feature_0",
   "importance": -1.3
}
```
Multi-class [class names are `foo`, `bar`, `baz`]
```
{ 
   “feature_name”: “feature_0”, 
   “importance”: 2.0, // sum(abs()) of class importances
   “foo”: 1.0, 
   “bar”: 0.5, 
   “baz”: -0.5 
},
```

For users to get the full benefit of aggregating and searching for feature importance, they should update their index mapping as follows (before turning this option on in their pipelines)
```
 "ml.inference.feature_importance": {
          "type": "nested",
          "dynamic": true,
          "properties": {
            "feature_name": {
              "type": "keyword"
            },
            "importance": {
              "type": "double"
            }
          }
        }
```
The mapping field name is as follows
`ml.<inference.target_field>.<inference.tag>.feature_importance`
if `inference.tag` is not provided in the processor definition, it is not part of the field path.
`inference.target_field` is defaulted to `ml.inference`.
//cc @lcawl ^ Where should we document this?

If this makes it in for 7.7, there shouldn't be any feature_importance at inference BWC worries as 7.7 is the first version to have it.

Refactor global build info plugin to leverage JavaInstallationRegistry (#54026)
This commit removes the configuration time vs execution time distinction
with regards to certain BuildParms properties. Because of the cost of
determining Java versions for configuration JDK locations we deferred
this until execution time. This had two main downsides. First, we had
to implement all this build logic in tasks, which required a bunch of
additional plumbing and complexity. Second, because some information
wasn't known during configuration time, we had to nest any build logic
that depended on this in awkward callbacks.

We now defer to the JavaInstallationRegistry recently added in Gradle.
This utility uses a much more efficient method for probing Java
installations vs our jrunscript implementation. This, combined with some
optimizations to avoid probing the current JVM as well as deferring
some evaluation via Providers when probing installations for BWC builds
we can maintain effectively the same configuration time performance
while removing a bunch of complexity and runtime cost (snapshotting
inputs for the GenerateGlobalBuildInfoTask was very expensive). The end
result should be a much more responsive build execution in almost all
scenarios.

Move pipeline agg validation to coordinating node (backport of #53669) (#54019)
This moves the pipeline aggregation validation from the data node to the
coordinating node so that we, eventually, can stop sending pipeline
aggregations to the data nodes entirely. In fact, it moves it into the
"request validation" stage so multiple errors can be accumulated and
sent back to the requester for the entire request. We can't always take
advantage of that, but it'll be nice for folks not to have to play
whack-a-mole with validation.

This is implemented by replacing `PipelineAggretionBuilder#validate`
with:
```
protected abstract void validate(ValidationContext context);
```

The `ValidationContext` handles the accumulation of validation failures,
provides access to the aggregation's siblings, and implements a few
validation utility methods.

[ML] adjusting feature importance mapping for multi-class support (#53821) (#54013)
Feature importance storage format is changing to encompass multi-class.

Feature importance objects are now mapped as follows
(logistic) Regression:
```
{
   "feature_name": "feature_0",
   "importance": -1.3
}
```
Multi-class [class names are `foo`, `bar`, `baz`]
```
{
   “feature_name”: “feature_0”,
   “importance”: 2.0, // sum(abs()) of class importances
   “foo”: 1.0,
   “bar”: 0.5,
   “baz”: -0.5
},
```

This change adjusts the mapping creation for analytics so that the field is mapped as a `nested` type.

Backport of async search changes (#53976)
* Get Async Search: omit _clusters section when empty (#53907)

The _clusters section is omitted by the search API whenever no remote clusters are searched. Async search should do the same, but Get Async Search returns a deserialized response, hence a weird `_clusters` section with all values set to `0` gets returned instead. In fact the recreated Clusters object is not the same object as the EMPTY constant, yet it has the same content.

This commit addresses this by changing the comparison in the `toXContent` method to not print out the section if the number of total clusters is `0`.

* Async search: remove version from response (#53960)

The goal of the version field was to quickly show when you can expect to find something new in the search response, compared to when nothing has changed. This can also be done by looking at the `_shards` section and `num_reduce_phases` returned with the search response. In fact when there has been one or more additional reduction of the results, you can expect new results in the search response. Otherwise, the `_shards` section could notify of additional failures of shards that have completed the query, but that is not a guarantee that their results will be exposed (only when the following partial reduction is performed their results will be available).

That said this commit clarifies this in the docs and removes the version field from the async search response

* Async Search: replicas to auto expand from 0 to 1 (#53964)

This way single node clusters that are green don't go yellow once async search is used, while
all the others still have one replica.

* [DOCS] address timing issue in async search docs tests (#53910)

The docs snippets for submit async search have proven difficult to test as it is not possible to guarantee that you get a response that is not final, even when providing `wait_for_completion=0`. In the docs we want to show though a proper long-running query, and its first response should be partial rather than final.

With this commit we adapt the docs snippets to show a partial response, and replace under the hood all that's needed to make the snippets tests succeed when we get a final response. Also, increased the timeout so we always get a final response.

[7.x][ML] Refactor DFA custom processor to cross validation splitter (#53915) (#53956)
While `CustomProcessor` is generic and allows for flexibility, there
are new requirements that make cross validation a concept it's hard
to abstract behind custom processor. In particular, we would like to
add data_counts to the DFA jobs stats. Counting training VS. test
docs would be a useful statistic. We would also want to add a
different cross validation strategy for multiclass classification.

This commit renames custom processors to cross validation splitters
which allows for those enhancements without cryptically doing
things as a side effect of the abstract custom processing.

Backport: initial data stream commit (#53959)
This commits adds a data stream feature flag, initial definition of a data stream and
the stubs for the data stream create, delete and get APIs. Also simple serialization
tests are added and a rest test to thest the data stream API stubs.

This is a large amount of code and mainly mechanical, but this commit should be
straightforward to review, because there isn't any real logic.

The data stream transport and rest action are behind the data stream feature flag and
are only intialized if the feature flag is enabled. The feature flag is enabled if
elasticsearch is build as snapshot or a release build and the
'es.datastreams_feature_flag_registered' is enabled.

The integ-test-zip sets the feature flag if building a release build, otherwise
rest tests would fail.

Yannick Welsch 060c72c799 Only link fd* files during source-only snapshot (#53463)
Source-only snapshots currently create a second full source-only copy of the shard on disk to
support incrementality during upload. Given that stored fields are occupying a substantial part
of a shard's storage, this means that clusters with source-only snapshots can require up to
50% more local storage. Ideally we would only generate source-only parts of the shard for the
things that need to be uploaded (i.e. do incrementality checks on original file instead of
trimmed-down source-only versions), but that requires much bigger changes to the snapshot
infrastructure. This here is an attempt to dramatically cut down on the storage used by the
source-only copy of the shard by soft-linking the stored-fields files (fd*) instead of copying
them.

Create API Key on behalf of other user (#53943)
This change adds a "grant API key action"

   POST /_security/api_key/grant

that creates a new API key using the privileges of one user ("the
system user") to execute the action, but creates the API key with
the roles of the second user ("the end user").

This allows a system (such as Kibana) to create API keys representing
the identity and access of an authenticated user without requiring
that user to have permission to create API keys on their own.

This also creates a new QA project for security on trial licenses and runs
the API key tests there

behavior, and NATIVE is not needed because it would always return true
since we should always have a basic license.
