* Allow multiple field names/patterns for (path_)(un)match (#66364)
Arrays of patterns are now allowed for dynamic_templates in the match,
unmatch, path_match and path_unmatch fields. DynamicTemplate has been modified to
support List<String> for these fields. The patterns can be either simple wildcards
or regex. As with previous functionality, when match_pattern="regex", simple wildcards
will be flagged with an error, but when match_pattern="simple", using regular expressions
in the match will not throw an error.
One new error pathway was added: if a user specifies a list of non-strings for
one of these pattern fields (e.g., "match": [10, false]) a MapperParserException
will be thrown.
A dynamic_template yamlRestTest was added. This is a BWC change, so the REST test
that uses arrays of patterns is limited to v8.9 and above.
Closes#66364.
The `data-streams/downsampling.asciidoc` test was missing a teardown clean of the ILM policies created. Due to this tests *do not have* the string `ilm` in its name, the automatic teardown process that cleans up the resources (check `ESRestTestCase.java#L815` & `DocsClientYamlTestSuiteIT.java` lines 177 & 195) is not executed for this specific test. In the case this test runs right before the `get-lifecycle` test, the policy won't be automatically deleted hence the test checking the version will fail. Finally, the order of execution of the test is not guaranteed by the suite.
This change at a high level adds global ranking on the coordinating node at the end of query reduction
prior to the fetch phase. Individual rank methods are defined in plugins.
The first rank plugin added as part of this change is reciprocal rank fusion (RRF). RRF uses a relatively
simple formula for merging 1...n results sets together with sum(1/(k+d)) where k is a ranking constant
and d is a document's scored position within a result set from a query.
This change adds:
* Total global ordinal build time for all fields and per field.
* Max shard value count per field. The value count is per shard and of the shard with the highest count. Reporting value on index level or across indices is too expensive to report or keep track of.
This is added to common stats, which
is exposed in several stats APIs.
The following api call:
```
GET /_nodes/stats?filter_path=nodes.*.indices.fielddata&fields=key,key2
```
Returns:
```
{
"nodes": {
"pcMNy4GsQ8ef6Rw-bI2EFg": {
"indices": {
"fielddata": {
"memory_size_in_bytes": 2552,
"evictions": 0,
"fields": {
"key2": {
"memory_size_in_bytes": 1320
},
"key": {
"memory_size_in_bytes": 1232
}
},
"global_ordinals": {
"build_time_in_millis": 8,
"fields": {
"key2": {
"build_time_in_millis": 4,
"shard_max_value_count": 4
},
"key": {
"build_time_in_millis": 4,
"shard_max_value_count": 4
}
}
}
}
}
}
}
}
```
This introduces an endpoint to reset the desired balance.
It could be used if computed balance diverged from the actual one a lot
to start a new computation from the current state.
This adds support for an index's index.lifecycle.origination_date setting in DLM. If an index has a
value for index.lifecycle.origination_date then it is used instead of the creation date or rollover
date (except in the case of the write index when the write index has not been rolled over yet).

Adds a new include flag definition_status to the GET trained models API.
When present the trained model configuration returned in the response
will have the new boolean field fully_defined if the full model definition
is exists.
Currently Lucene limits the max number of vector dimensions to 1024.
This commit overrides KnnFloatVectorField and KnnByteVectorField
classes to increase the limit to 2048 for indexed vectors in ES.
This changes the `GET _data_stream/ds_name/_lifecycle` endpoint to
return the data stream name even if it doesn't have a lifecycle
configured.
e.g.
```
{
"data_streams": [
{
"name": "logs-nginx"
}
]
}
```
* Fix xcontent and tests
* Update docs

This removes a redundant `lifecycle` field in the `PUT _lifecycle`
request.
Before we had
```
PUT _data_stream/logs-nginx/_lifecycle
{
"lifecycle": {
"data_retention": "7d"
}
}
```
This changes the request to
```
PUT _data_stream/logs-nginx/_lifecycle
{
"data_retention": "7d"
}
```
Here we add synthetic source support for fields whose type is flattened.
Note that flattened fields and synthetic source have the following limitations,
all arising from the fact that in synthetic source we just see key/value pairs
when reconstructing the original object and have no type information in mappings:
* flattened fields use sorted set doc values of keywords, which means two things:
first we do not allow duplicate values, second we treat all values as keywords
* reconstructing array of objects results in nested objects (no array)
* reconstructing arrays with just one element results in a single-value field since we
have no way to distinguish single-valued from multi-values fields other then looking
at the count of values
