Currently if distance_feature query contains boost,
it incorrectly gets applied twice: in AbstractQueryBuilder::toQuery and
we also pass this boost to Lucene's LongPoint.newDistanceFeatureQuery.
As a result we get incorrect scores.
This fixes this error to ensure that boost is applied only once.

The original description of per-field boosting is incorrect. Boosting a
field does not imply that it is more important relative to other fields.
It simply means that the score is multiplied by the supplied boost
value. Due to the differences in each field's term and document
statistics, it's not possible to imply relative importance of fields
based on the per-field boost value alone.

The current _update_by_query documentation mentions a scroll_size default of 100 and later another default of 1000.
We use the default of 1000 defined in AbstractBulkByScrollRequest and this PR changes the documentation accordingly.
Closes#63637
For a query like `SELECT name FROM test WHERE name LIKE ''%c*'` ES SQL
generates an error. `*` is not a special character in a `LIKE` construct
and it's expected to not needing to be escaped, so the previous query
should work as is.
In the LIKE pattern any `*` character was treated as invalid character
and the usage of `%` or `_` was suggested instead. But `*` is a valid,
acceptable non-wildcard on the right side of the `LIKE` operator.

As a result of this, we can remove a chunk of code from TypeParsers as well. Tests
for search/index mode analyzers have moved into their own file. This commit also
rationalises the serialization checks for parameters into a single SerializerCheck
interface that takes the values includeDefaults, isConfigured and the value
itself.

This PR adds deprecation warnings when accessing System Indices via the REST layer. At this time, these warnings are only enabled for Snapshot builds by default, to allow projects external to Elasticsearch additional time to adjust their access patterns.
Deprecation warnings will be triggered by all REST requests which access registered System Indices, except for purpose-specific APIs which access System Indices as an implementation detail a few specific APIs which will continue to allow access to system indices by default:
- `GET _cluster/health`
- `GET {index}/_recovery`
- `GET _cluster/allocation/explain`
- `GET _cluster/state`
- `POST _cluster/reroute`
- `GET {index}/_stats`
- `GET {index}/_segments`
- `GET {index}/_shard_stores`
- `GET _cat/[indices,aliases,health,recovery,shards,segments]`
Deprecation warnings for accessing system indices take the form:
```
this request accesses system indices: [.some_system_index], but in a future major version, direct access to system indices will be prevented by default
```
The current link points to an obsolete site, which is no longer maintained.

This fixes fields retrieval on unsigned_long field
1) For docvalue_fields a custom UnsignedLongLeafFieldData::getLeafValueFetcher
is implemented that correctly retrieves doc values.
2) For stored fields, an error was fixed in UnsignedLongFieldMapper
how stored values were stored. Before they were incorrectly
stored in the shifted format, now they are stored as original
values in String format.

We support `"""` in `console` snippets to emulate kibana's CONSOLE.
CONSOLE also spits out `"""` when a json field contains a new line or a
double quote. This adds support for those sorts of responses to the
handling of `console-response` snippets.
Revises the current 'How to avoid oversharding' docs to incorporate

* Creates a "Fix an oversharded cluster" section

Introduce 64-bit unsigned long field type
This field type supports
- indexing of integer values from [0, 18446744073709551615]
- precise queries (term, range)
- precise sort and terms aggregations
- other aggregations are based on conversion of long values
to double and can be imprecise for large values.

(cherry picked from commit da511f4e033db6e8a6aa2a54b23e906b5e026845)
This PR adds a new 'version' field type that allows indexing string values
representing software versions similar to the ones defined in the Semantic
Versioning definition (semver.org). The field behaves very similar to a
'keyword' field but allows efficient sorting and range queries that take into
accound the special ordering needed for version strings. For example, the main
version parts are sorted numerically (ie 2.0.0 < 11.0.0) whereas this wouldn't
be possible with 'keyword' fields today.
Valid version values are similar to the Semantic Versioning definition, with the
notable exception that in addition to the "main" version consiting of
major.minor.patch, we allow less or more than three numeric identifiers, i.e.
"1.2" or "1.4.6.123.12" are treated as valid too.

The autoscaling decision API now returns an absolute capacity,
and leaves the actual decision of whether a scale up or down
is needed to the orchestration system.
The decision API now returns both a tier and node level required
and current capacity as wells as a decider level breakdown of the
same though with in particular current memory still not populated.
This commit adds the `index.routing.allocation.prefer._tier` setting to the
`DataTierAllocationDecider`. This special-purpose allocation setting lets a user specify a
preference-based list of tiers for an index to be assigned to. For example, if the setting were set
to:
```
"index.routing.allocation.prefer._tier": "data_hot,data_warm,data_content"
```
If the cluster contains any nodes with the `data_hot` role, the decider will only allow them to be
allocated on the `data_hot` node(s). If there are no `data_hot` nodes, but there are `data_warm` and
`data_content` nodes, then the index will be allowed to be allocated on `data_warm` nodes.
This allows us to specify an index's preference for tier(s) without causing the index to be
unassigned if no nodes of a preferred tier are available.
Subsequent work will change the ILM migration to make additional use of this setting.

This commit adjusts the following APIs so now they not only support an `_all` case, but wildcard patterned Ids as well.
- `GET _ml/calendars/<calendar_id>/events`
- `GET _ml/calendars/<calendar_id>`
- `GET _ml/anomaly_detectors/<job_id>/model_snapshots/<snapshot_id>`
- `DELETE _ml/anomaly_detectors/<job_id>/_forecast/<forecast_id>`
We removed index-time boosting back in 5x, and we no longer document the 'boost'
parameter on any of our mapping types. However, it is still possible to define an
index-time boost on a field mapper for a surprisingly large number of field types, and
they even have an effect (sometimes, on some queries).
As a first step in finally removing all traces of index time boosting, this comment emits
a deprecation warning whenever a boost parameter is found on a mapping definition.
