* Adding shard count to _nodes/stats api
Added a shards section to each node returned by the _nodes/stats api. Currently this new section only contains a total count of all shards on the node.
The current `ids` option doesn't allow pinning a specific document in a
single index when searching over multiple indices. This introduces a
`documents` option, which is an array of `_id` and `_index`
fields to allow index-specific pins.
Closes https://github.com/elastic/elasticsearch/issues/67855.
A tag is required to reuse Elasticsearch breaking changes in the Stack
Guide. To display properly, the breaking changes must use external
links rather than xrefs.
This PR correctly places those tags for reuse. It also replaces
several xrefs with external links for reuse.
Changes:
* Updates the Kibana dev console screenshots to use the new EUI theme
* Corrects an example SQL query in one screenshot. The previous screenshot used `_/sql`, which is not a valid URI.
Adds formal API docs for the following APIs:
* Clear SQL cursor
* SQL search
* SQL translate
Other changes:
* Removes and redirects the "Supported REST parameters section." This is now covered in the SQL search API docs.
* Updates a few related xrefs.
Closes#75085
In the upcoming Lucene 9 release, `indices.query.bool.max_clause_count` is
going to apply to the entire query tree rather than per `bool` query. In order
to avoid breaks, the limit has been bumped from 1024 to 4096.
The semantics will effectively change when we upgrade to Lucene 9, this PR
is only about agreeing on a migration strategy and documenting this change.
To avoid further breaks, I am leaning towards keeping the current setting name
even though it contains `bool`. I believe that it still makes sense given that
`bool` queries are typically the main contributors to high numbers of clauses.

Today the docs for remote cluster connections use `ping_schedule` fairly
liberally, and don't mention that you should prefer TCP keepalives
wherever possible. This commit reduces the use of this setting in the
examples and adjusts the description of the setting to include a note
about TCP keepalives instead.
Date histogram interval parameter was deprecated in 7.2, in favor of the more specific fixed_interval and calendar_interval parameters. The old logic used some poorly understood guessing to decide if it should operate in fixed or calendar mode. The new logic requires a specific choice by the user, which is more explicit. In 7.x REST compatibility mode, we will parse the interval as calendar if possible, and otherwise interpret it as fixed.
This change introduces a CLI tool that can be used to create
enrollment tokens. It doesn't require credentials, but simply
write access to the local filesystem of a node. It uses an
auto-generated user in the file-realm with superuser role.
For this purpose, this change also introduces a base class for a
CLI tool that can be used by any CLI tool needs to perform actions
against an ES node as a superuser without requiring credentials
from the user. It is worth noting that this doesn't change our
existing thread model, because already an actor with write access
to the fs of an ES node, can become superuser (again, by
adding a superuser to the file realm, albeit manually).
Changes:
* Adds an example script for removing a subfield from an object
* Makes several other example snippets more modular.

* Allow ILM move-to-step without `action` or `name`
This commit enhances ILM's move-to-step API to allow dropping the `name`, or dropping both the
`action` and `name`. For example:
```json
POST /_ilm/move/foo-1
{
"current_step": {
"phase": "hot",
"action": "rollover",
"name": "check-rollover-ready"
},
"next_step": {
"phase": "warm",
"action": "forcemerge"
}
}
```
Will move to the first step in the `forcemerge` action in the `warm` phase (without having to know
the specific step name).
Another example:
```json
POST /_ilm/move/foo-1
{
"current_step": {
"phase": "hot",
"action": "rollover",
"name": "check-rollover-ready"
},
"next_step": {
"phase": "warm"
}
}
```
Will move to the first step in the `warm` phase (without having to know the specific action name).
Bear in mind that the execution order is still entirely an implementation detail, so "first" in the
above sentences means the first step that ILM would execute.

* Log index and policy name when the concrete step key can't be resolved

Changes:
* Documents the `dimension` mapping parameter for `ip`, `keyword`, and `numeric`
fields.
* Documents the `index.mapping.dimension_fields.limit` index setting.
By default, `logger.deprecation.level` logs messages at the `DEPRECATION` level. This updates
and reorganizes the related docs.

In theory, Elasticsearch supported configuring a PKCS#11 keystore
anywhere where a keystore/truststore could be used. For example:
xpack.security.http.ssl.keystore.type: pkcs11
However, this support was poorly tested and broken.
This commit removes PKCS#11 support from any configurable SSL context.
It does not affect the ability to use a PKCS#11 keystore as the JRE's
system default keystore/truststore.
Fixes a broken link in the `documentation.url` for the field usage stats API and
enroll Kibana API.
These broken links caused the build for the JS client docs to fail.

Adds a field usage API that reports shard-level statistics about which Lucene fields have been accessed, and which
parts of the Lucene data structures have been accessed.
Field usage statistics are automatically captured when queries are runnning on a cluster. A shard-level search request
that accesses a given field, even if multiple times during that request, is counted as a single use.
We have already decided not to have xpack usage for field mappers
(see #53076). As mappings stats of all fields is already tracked
in cluster stats.
Moreover xpack usage for vector field is a quite expensive operation
(see #74974).
This removes xpack actions for vector field.
Adds formal API docs and JSON specs for the following APIs:
* Get async SQL search
* Get async SQL search status
* Delete async SQL search
