Backport from #52179
Don't rely on the delete index api to resolve all the enrich indices for a particular enrich policy using a '[policy_name]-*' wildcard expression. With this change, the delete policy api will resolve the indices to remove and pass that directly to the delete index api.
This resolves a bug, that if `action.destructive_requires_name` setting has been set to true then the delete policy api is unable to remove the enrich indices related to the policy being deleted.

The shard follow task cleaner executes on behalf of the user to clean up
a shard follow task after the follower index has been
deleted. Otherwise, these persistent tasks are left laying around, and
they fail to execute because the follower index has been deleted. In the
face of security, attempts to complete these persistent tasks would
fail. This is because these cleanups are executed under the system
context (this makes sense, they are happening on behalf of the user
after the user has executed an action) but the system role was never
granted the permission for persistent task completion. This commit
addresses this by adding this cluster privilege to the system role.
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)

The `top_metrics` agg is kind of like `top_hits` but it only works on
doc values so it *should* be faster.
At this point it is fairly limited in that it only supports a single,
numeric sort and a single, numeric metric. And it only fetches the "very
topest" document worth of metric. We plan to support returning a
configurable number of top metrics, requesting more than one metric and
more than one sort. And, eventually, non-numeric sorts and metrics. The
trick is doing those things fairly efficiently.

ML mappings and index templates have so far been created
programmatically. While this had its merits due to static typing,
there is consensus it would be clear to maintain those in json files.
In addition, we are going to adding ILM policies to these indices
and the component for a plugin to register ILM policies is
`IndexTemplateRegistry`. It expects the templates to be in resource
json files.
For the above reasons this commit refactors ML mappings and index
templates into json resource files that are registered via
`MlIndexTemplateRegistry`.

This commit makes the names of fetch subphases more consistent:
* Now the names end in just 'Phase', whereas before some ended in
'FetchSubPhase'. This matches the query subphases like AggregationPhase.
* Some names include 'fetch' like FetchScorePhase to avoid ambiguity about what
they do.
Ironically PreventFailingBuildIT.testSoThatTestsDoNotFail is causing failures
as documented in #52197. The no longer serves a purpose and can now be removed.
This is to support the ML categorization wizard.
Currently cluster:admin/analyze is only provided with the
"manage" cluster privilege, which is an excessive privilege
level to provide access to this single feature. It means
that the ML categorization wizard only works for extremely
highly privileged users.
Following this change the Kibana system user will be
permitted to run the _analyze endpoint on supplied strings
(not on an index). The ML UI will then call the _analyze
endpoint as the Kibana system user after first checking
that the logged-in user is permitted to create an ML job.
This will mean that users with the more reasonable
"manage_ml" cluster privilege will be permitted to use
the ML categorization wizard.
(This is also consistent with the way the ML UI will access
_all_ Elasticsearch functionality when the "ML in Spaces"
project is completed.)

Previously, in the in-memory sorting module
`LocalAggregationSorterListener` only the aggregate functions where used
(grabbed by the `sortingColumns`). As a consequence, if the ORDER BY
was also using columns of the GROUP BY clause, (especially in the case
of higher priority - before the aggregate functions) wrong results were
produced. E.g.:
```
SELECT gender, MAX(salary) AS max FROM test_emp
GROUP BY gender
ORDER BY gender, max
```
Add all columns of the ORDER BY to the `sortingColumns` so that the
`LocalAggregationSorterListener` can use the correct comparators in
the underlying PriorityQueue used to implement the in-memory sorting.

Previously, when the specified (or default) fetchSize led to
subsequent HTTP requests and the usage of cursors, those subsequent

(with the correct timezone) the processing of the query results by
the HitExtractors in the next pages was done using the default
timezone Z. This could lead to incorrect results.
Fix the issue by correctly using the initially specified timezone,
which is found in the deserialisation of the cursor string.

Currently, the logic for looking up `flattened` field types lives in the
top-level `FieldTypeLookup`. This PR moves it into a dedicated class
`DynamicKeyFieldTypeLookup`.
This fixes:
- the parsing of milliseconds in intervals: everything past the . used to be converted as-is to milliseconds, with no normalisation of the unit; thus, a value of .23 ended up as 23 millis in the interval, instead of 230.
- the printing of a trailing .0, in case the interval lacks the fractional part;
- tests generating a random millisecond value used to simply print it in the string about to be evaluated without a necessary front-filling of 0[s], where the amount was below 100/10.
(The combination of first and last issues above, plus statistical "luck" made the incorrect handling pass the tests.)

* 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

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.

The REST tests for autoscaling either need to be skipped in a
non-snapshot build, or alternatively, the feature flag registered so
that autoscaling can be enabled. We prefer the latter approach, as it
allows us to also test autoscaling in non-snapshot builds incrementally,
instead of at the end of development as autoscaling prepares for
release. This commit registers the autoscaling feature flag in REST
tests for non-snapshot builds.
We can just put the `IndexId` instead of just the index name into the recovery soruce and
save one load of `RepositoryData` on each shard restore that way.
Add some more tests where more than one literal is selected,

when autoscaling is ready for release.

(cherry picked from commit 9f414a8d05c75e1a9f8250084f6dcd634d5d78d8)
The main purpose of this commit is to add a single autoscaling REST
endpoint skeleton, for the purpose of starting to build out the build
and testing infrastructure that will surround it. For example, rather
than commiting a fully-functioning autoscaling API, we introduce here
the skeleton so that we can start wiring up the build and testing
infrastructure, establish security roles/permissions, an so on. This
way, in a forthcoming PR that introduces actual functionality, that PR
will be smaller and have less distractions around that sort of
infrastructure.
If the configs are removed (by some horrific means), we should still allow tasks to be cleaned up easily.
Datafeeds and jobs with missing configs are now visible in their respective _stats calls and can be stopped/closed.
Not all clients support this e.g if the java high level rest client were
to map this it would look like `client.cat().ml().api()` which hinders
discoverability.

This change ensures that the rewrite of the shard request is executed in the network thread or in the refresh listener when waiting for an active shard. This allows queries that rewrite to match_no_docs to bypass the search thread pool entirely even if the can_match phase was skipped (pre_filter_shard_size > number of shards). Coordinating nodes don't have the ability to create empty responses so this change also ensures that at least one shard creates a full empty response while the other can return null ones. This is needed since creating true empty responses on shards require to create concrete aggregators which would be too costly to build on a network thread. We should move this functionality to aggregation builders in a follow up but that would be a much bigger change.
This change is also important for #49601 since we want to add the ability to use the result of other shards to rewrite the request of subsequent ones. For instance if the first M shards have their top N computed, the top worst document in the global queue can be pass to subsequent shards that can then rewrite to match_no_docs if they can guarantee that they don't have any document better than the provided one.
When clenaing a shard follow task after an index has been deleted, an
exception can occur submitting the complete persistent task
action. However, this exception message is not logged. This commit
addresses this by including the exception that led to the failure in the
log message.
AutoFollowIT tests are regularly failing on CI because they rely
on how cluster state updates are processed within the integration
clusters. We tried to limit this in #49141 by moving to latches
instead of waiting for assertions to pass but there are still some
places were it still need to wait for the cluster state updates to
be processed and auto-follow stats to be updated.
This commit gives more time to assertBusy() that verifies the
AutoFollowStats (up to 60 seconds) and also always log the
auto-follow stats in case the assertions failed.

Currently, the same class `FieldCapabilities` is used both to represent the

help clarify the logic, this PR proposes to create a separate class
`IndexFieldCapabilities` for the capabilities in one index. The refactor will
also help when adding `source_path` information in #49264, since the merged
source path field will have a different structure from the field for a single index.

* Add a new class IndexFieldCapabilities.
* Remove extra constructor from FieldCapabilities.
* Combine the add and merge methods in FieldCapabilities.Builder.
The work to switch file upload over to treating delimited files
like semi-structured text and using the ingest pipeline for CSV
parsing makes the multi-line start pattern used for delimited
files much more critical than it used to be.
Previously it was always based on the time field, even if that
was towards the end of the columns, and no multi-line pattern
was created if no timestamp was detected.
This change improves the multi-line start pattern by:
1. Never creating a multi-line pattern if the sample contained
only single line records. This improves the import
efficiency in a common case.
2. Choosing the leftmost field that has a well-defined pattern,
whether that be the time field or a boolean/numeric field.
This reduces the risk of a field with newlines occurring
earlier, and also means the algorithm doesn't automatically
fail for data without a timestamp.
Adds a secure and reloadable SECURE_AUTH_PASSWORD setting to allow keystore entries in the form "xpack.monitoring.exporters.*.auth.secure_password" to securely supply passwords for monitoring HTTP exporters. Also deprecates the insecure `AUTH_PASSWORD` setting.
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.

* Fix the "slices" parameter for the Delete By Query API in the REST specification (#51535)
This patch updates the `type` parameter in the Delete By Query API: according to
[the documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-delete-by-query.html#docs-delete-by-query-slice),
it can be set to "auto", but the type in the documentation allows only numerical values.
This prevents people from setting the parameter to "auto" eg. in the Go client,
which generates source from the specification, and sets the corresponding Go
type as number.
The patch uses the `|` notation, which we have discussed previously for encoding
a "polymorphic" parameter like this.

* Fix the Enrich API documentation in REST specification (#51528)
This patch fixes the REST API documentation for the Enrich APIs to conform to the current schema.
(cherry picked from commit 59f28f4f2feeba3f6d2f0b632410577eacb28121)
do index refresh of the internal transform index with the system user
instead of using the calling user which does not have sufficient rights
if security is enabled
fixes#51728
While we use `== false` as a more visible form of boolean negation
(instead of `!`), the true case is implied and the true value does not
need to explicitly checked. This commit converts cases that have slipped
into the code checking for `== true`.
* Fix SnapshotLifecycleRestIT.testFullPolicySnapshot
This previously was missing some key information in the output of the failure. This captures that
information and adds logging at each step so we can determine the cause *if* it fails again.
Resolves#50358
This setting was introduced with the purpose of reducing the time took by
tests that shut nodes down. Tests like `MlDistributedFailureIT` and
`NetworkDisruptionIT`. However, it is unfortunate to have to set the value
to an explicit value in production. In addition, and most important, the dynamically
choosing the value for this setting makes it impossible to adopt static index template configs
that we register via `IndexTemplateRegistry`, which we need to use in order to start
registering ILM policies for the ML indices.
This commit removes this setting from our templates. I run the tests a few times and could
not see execution time differing significantly.
Backport of #51740
This addresses another race condition that could yield this test flaky.

* Change index.lifecycle.step.master_timeout to indices.lifecycle.step.master_timeout
This changes setting name from `index.lifecycle.step.master_timeout` to
`indices.lifecycle.step.master_timeout` to avoid confusion about its scope.
`index.*` settings are recognized as index level settings, this one is node level.
Reletes to #51698
Currently when an ILM policy finishes its execution, the index moves into the `TerminalPolicyStep`,
denoted by a completed/completed/completed phase/action/step lifecycle execution state.
This commit changes the behavior so that the index lifecycle execution state halts at the last
configured phase's `PhaseCompleteStep`, so for instance, if an index were configured with a policy
containing a `hot` and `cold` phase, the index would stop at the `cold/complete/complete`
`PhaseCompleteStep`. This allows an ILM user to update the policy to add any later phases and have
indices configured to use that policy pick up execution at the newly added "later" phase. For
example, if a `delete` phase were added to the policy specified about, the index would then move
from `cold/complete/complete` into the `delete` phase.

This adds logic to handle paging problems when the ID pattern + tags reference models stored as resources.
Most of the complexity comes from the issue where a model stored as a resource could be at the start, or the end of a page or when we are on the last page.
The changes are to help users prepare for migration to next major
release (v8.0.0) regarding to the break change of realm order config.
Warnings are added for when:
* A realm does not have an order config
* Multiple realms have the same order config
The warning messages are added to both deprecation API and loggings.
The main reasons for doing this are: 1) there is currently no automatic relay
between the two; 2) deprecation API is under basic and we need logging
for OSS.
This commit switches the strategy for managing dot-prefixed indices that
should be hidden indices from using "fake" system indices to an explicit
exclusions list that must be updated when those indices are converted to
hidden indices.
* Optimize not-equalities in con-/disjunctions
This commit adds optimisations of not-equalities in conjunctions and
disjunctions:
* for conjunctions, the not-equality can be optimized away when applied
together with a range or inequality, in case the not-equality point
falls outside the domain of the later condition; if its on the boarder,
it will modify the bound, to simply exclude the equality, if present;
otherwise no optimisation can be applied;
* for disjunctions, the not-equals could filter away the ranges and
inequalities, unless these include an equality on the bound, in which
case the entire condition becomes always true, but this would influence
the score() function, so it's been omitted;
* fix aggregations of inequalities in ranges
This commit fixes the loop that aggregates inequalities into ranges:
- it won't advance the outer loop index in case of a merge, since the
current element is removed;
- it will break the inner loop, since comparision against the element
selected in the outer loop can't continue, as it had been removed.

* Rename ILM history index enablement setting
The previous setting was `index.lifecycle.history_index_enabled`, this commit changes it to
`indices.lifecycle.history_index_enabled` to indicate this is not an index-level setting (it's node
level).
* [ML][Inference] Fix weighted mode definition (#51648)
Weighted mode inaccurately assumed that the "max value" of the input values would be the maximum class value. This does not make sense.
Weighted Mode should know how many classes there are. Hence the new parameter `num_classes`. This indicates what the maximum class value to be expected.
We need to force flush to make the last commit safe; otherwise, we might
fail to open FrozenEngine. Note that we force flush before closing a
shard.
Closes#51620
Three fixes for when the `compressed_definition` is utilized on PUT
* Update the inflate byte limit to be the minimum of 10% the max heap, or 1GB (what it was previously)
* Stream data directly to the JSON parser, so if it is invalid, we don't have to inflate the whole stream to find out
* Throw when the maximum bytes are reach indicating that is why the request was rejected
Previously, if YEAR() was used as and ORDER BY argument without being
wrapped with another scalar (e.g. YEAR(birth_date) + 10), no script
ordering was used but instead the underlying field (e.g. birth_date)
was used instead as a performance optimisation. This works correctly if
YEAR() is the only ORDER BY arg but if further args are used as tie
breakers for the ordering wrong results are produced. This is because
2 rows with the different birth_date but on the same year are not tied
as the underlying ordering is on birth_date and not on the
YEAR(birth_date), and the following ORDER BY args are ignored.
Remove this optimisation for YEAR() to avoid incorrect results in
such cases.
As a consequence another bug is revealed: scalar functions on top
of nested fields produce scripted sorting/filtering which is not yet
supported. In such cases no error was thrown but instead all values for
such nested fields were null and were passed to the script implementing
the sorting/filtering, producing incorrect results.
Detect such cases and throw a validation exception.

Add a verification that full-text search functions `MATCH()` and `QUERY()`
are not allowed in the SELECT clause, so that a nice error message is
returned to the user early instead of an "ugly" exception.

This commit creates a new index privilege named `maintenance`.
The privilege grants the following actions: `refresh`, `flush` (also synced-`flush`),
and `force-merge`. Previously the actions were only under the `manage` privilege
which in some situations was too permissive.

Datafeeds being closed while starting could result in and NPE. This was
handled as any other failure, masking out the NPE. However, this
conflicts with the changes in #50886.

This PR tries to address the intermittent vector test failures on 7.x by making
sure we create indices with one shard.
The fix is based on this theory as to what's happening:
* On 7.x, the default number of shards is 1, but in REST tests we randomly use
2 in order to cover the multiple shards case. In the failing test run, we use 2
shards and all documents end up on only one shard.
* During a search, the response from the empty shard doesn't produce
deprecation warnings because we never try to execute the script. If not all
shard responses contain the warning headers, then certain deprecation warnings
can be lost (due to the bug described in #33936).
Addresses #50716.

Prior to the change the watcher index listener didn't implement the
`postIndex(ShardId, Engine.Index, Engine.IndexResult)` method. This
caused document level exceptions like VersionConflictEngineException
to be ignored. This commit fixes this.
The watcher indexing listener did implement the `postIndex(ShardId, Engine.Index, Exception)`
method, but that only handles engine level exceptions.
This change also unmutes the SmokeTestWatcherTestSuiteIT#testMonitorClusterHealth test again.

Previous the formatter was breaking simple if/else statements (i.e.
without braces) onto separate lines, which could be fragile because the
formatter cannot also introduce braces. Instead, keep such expressions
on the same line.
The timeout.tcp_read AD/LDAP realm setting, despite the low-level
allusion, controls the time interval the realms wait for a response for
a query (search or bind). If the connection to the server is synchronous
(un-pooled) the response timeout is analogous to the tcp read timeout.
But the tcp read timeout is irrelevant in the common case of a pooled
connection (when a Bind DN is specified).
The timeout.tcp_read qualifier is hereby deprecated in favor of
timeout.response.
In addition, the default value for both timeout.tcp_read and
timeout.response is that of timeout.ldap_search, instead of the 5s (but
the default for timeout.ldap_search is still 5s). The
timeout.ldap_search defines the server-controlled timeout of a search
request. There is no practical use case to have a smaller tcp_read
timeout compared to ldap_search (in this case the request would time-out
on the client but continue to be processed on the server). The proposed
change aims to simplify configuration so that the more common
configuration change, adjusting timeout.ldap_search up, has the expected
result (no timeout during searches) without any additional
modifications.
Closes#46028
In the SQL with SSL tests, we need to find the interfaces that are up,
are loopback devices, or have a loopback address. If we check if the
device is up first, we can run into situations where the device is a
virtual ethernet device that might have disappeared between us seeing
the device, and checking if it is up. By first checking if the device is
a loopback device or it has a loopback address, then we can avoid
checking if the device is up except for loopback devices and therefore
we can avoid the disappearing virtual ethernet device problem.
* Allow Repository Plugins to Filter Metadata on Create
Add a hook that allows repository plugins to filter the repository metadata
before it gets written to the cluster state.
This commit deprecates the creation of dot-prefixed index names (e.g.
.watches) unless they are either 1) a hidden index, or 2) registered by
a plugin that extends SystemIndexPlugin. This is the first step
towards more thorough protections for system indices.
This commit also modifies several plugins which use dot-prefixed indices
to register indices they own as system indices, and adds a plugin to
register .tasks as a system index.
The docs tests have recently been running much slower than before (see #49753).
The gist here is that with ILM/SLM we do a lot of unnecessary setup / teardown work on each
test. Compounded with the slightly slower cluster state storage mechanism, this causes the
tests to run much slower.
