Adds normalisation of ngram tokens to reduce disk space.
All punctuation becomes / char and for A-Z0-9 chars turn even codepoints to prior odd e.g. aab becomes aaa

Currently, CAST will use the first keyword subfield of a text field for
an expression in WHERE clause that gets translated to a painless script
which will lead to an exception thrown:
```
"root_cause": [
{
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"org.elasticsearch.index.mapper.TextFieldMapper$TextFieldType.fielddataBuilder(TextFieldMapper.java:759)",
"org.elasticsearch.index.fielddata.IndexFieldDataService.getForField(IndexFieldDataService.java:116)",
"org.elasticsearch.index.query.QueryShardContext.lambda$lookup$0(QueryShardContext.java:308)",
"org.elasticsearch.search.lookup.LeafDocLookup$1.run(LeafDocLookup.java:101)",
"org.elasticsearch.search.lookup.LeafDocLookup$1.run(LeafDocLookup.java:98)",
"java.security.AccessController.doPrivileged(Native Method)",
"org.elasticsearch.search.lookup.LeafDocLookup.get(LeafDocLookup.java:98)",
"org.elasticsearch.search.lookup.LeafDocLookup.get(LeafDocLookup.java:41)",
"org.elasticsearch.xpack.sql.expression.function.scalar.whitelist.InternalSqlScriptUtils.docValue(InternalSqlScriptUtils.java:79)",
"InternalSqlScriptUtils.cast(InternalSqlScriptUtils.docValue(doc,params.v0),params.v1)",
" ^---- HERE"
],
"script": "InternalSqlScriptUtils.cast(InternalSqlScriptUtils.docValue(doc,params.v0),params.v1)",
"lang": "painless"
}
],
```
Instead of allowing a painless translation using the first underlying
keyword silently, which can be confusing, we detect such usage and throw\
an error early.

In #22721, the decision to throttle indexing was inadvertently flipped,
so that we until this commit throttle indexing during recovery but
never throttle user initiated indexing requests. This commit
fixes that to throttle user initiated indexing requests and never
throttle recovery requests.

Backport #63170 to 7.x branch.
The _index field is a special field that allows using queries against the name of an index or alias.
Data stream names were not included, this pr fixes that by changing SearchIndexNameMatcher
(which used via IndexFieldMapper) to also include data streams.
We recently upgraded the SDK which resulted in the storage exception to be
wrapped now so we must unwrap to check for whether it's a 404 or not.

Splitting some tests out of this class that has become a catch-all
for random snapshot related tests into either existing suits that fit
better for these tests or one of two new suits to prevent timeouts
in extreme cases (e.g. `WindowsFS` + many nodes + multiple data paths per node).
No other changes to tests were made whatsoever.
Closes#61541
Use triple double quotes enclosing a string literal to interpret it
as unescaped, in order to use `?` for marking query params and avoid
user confusion. `?` also usually implies regex expressions.
Any character inside the `"""` beginning-closing markings is considered
raw and the only thing that is not permitted is the `"""` sequence itself.
If a user wants to use that, needs to resort to the normal `"` string literal
and use proper escaping.

* [ML] renames */inference* apis to */trained_models* (#63097)
This commit renames all `inference` CRUD APIs to `trained_models`.
This aligns with internal terminology, documentation, and use-cases.
In the codebase there is the non-written convention that classes that extend `MappedFieldType` are generally called `*FieldType`. With this commit we adopt the same convention for runtime field types which allows us to shorten their names by removing the `Mapped` portion which is implicit.
We would only check for a null value and not for an empty string so
that meant that we were not actually enforcing this mandatory
setting. This commits ensures we check for both and fail
accordingly if necessary, on startup
7.x client can pass media type with a version which will return a 7.x
version of the api in ES 8.
In ES server 7 this media type shoulld be accepted but it serve the same
version of the API (7x)

* Add System Indices check to AutoCreateIndex
By default, Elasticsearch auto-creates indices when a document is
submitted to a non-existent index. There is a setting that allows users
to disable this behavior. However, this setting should not apply to
system indices, so that Elasticsearch modules and plugins are able to
use auto-create behavior whether or not it is exposed to users.
This commit constructs the AutoCreateIndex object with a reference to
the SystemIndices object so that we bypass the check for the user-facing
autocreate setting when it's a system index that is being autocreated.
We also modify the logic in TransportBulkAction to make sure that if a
system index is included in a bulk request, we don't skip the
autocreation step.
Since `fork` is not used, is undocumented in Python EQL and
there is no plan at the moment to implement it in the future,
removing it from the grammar. User will get parsing exceptions
instead of higher level messages about unsupported features
which can lead to wrong expectations.

Currently we read in 64KB blocks from the network. When TLS is not
enabled, these bytes are normally passed all the way to the application
layer (some exceptions: compression). For the HTTP layer this means that
these bytes can live throughout the entire lifecycle of an indexing
request.
The problem is that if the reads from the socket are small, this means
that 64KB buffers can be consumed by 1KB or smaller reads. If the socket
buffer or TCP buffer sizes are small, the leads to massive memory
waste. It has been identified as a major source of OOMs on coordinating
nodes as Elasticsearch easily exhausts the heap for these network bytes.
This commit resolves the problem by placing a handler after the TLS
handler to copy these bytes to a more appropriate buffer size as
necessary. This comes after TLS, because TLS is a framing layer which
often resolves this problem for us (the 64KB buffer will be decoded
into a more appropriate buffer size). However, this extra handler will
solve it for the non-TLS pipelines.
This adds the network property from the MaxMind Geo ASN database.
This enables analysis of IP data based on the subnets that MaxMind have
previously identified for ASN networks.

This test accesses system indices for 2 reasons.
First, it creates a filter that has a different type. This was done
to assert that filter is not returned from the APIs. However,
now that access to the `.ml-meta` index is restricted,
it is not really a concern.
Second, it creates a `.ml-meta` index without mappings to test
the get API does not fail due to lack of mappings on a sorted field,
namely the `filter_id`. Once again, this test is less useful once
system indices have restricted access.

Backport of #63111
Bouncy Castle's BC-FJA-1.0.2 has been certified for a while now
but we had noticed that it seems to be rather entropy hungry and
ES would start very slowly ( and tests would take forever )
because of blocking calls to /dev/random.
We verified that this is resolved when enabling hw RNG or a
software one like haveged. While rng-tools should be suggested for
production uses, our ephemeral workers have haveged installed
which should work just fine for CI.

This fixes a bug introduced when moving from mget to ids query. While
mget returns all the ids given, id query is a search query and thus by
default returns only 10 documents.
The fix correctly sets the expected size so all the information is
returned inside the response.

It extracts the query capabilities from AbstractGeometryFieldType into two new interfaces, GeoshapeQueryable and ShapeQueryable. Those interfaces are implemented by the final mappers.
Bwc tests can consume much time to build and to run so it's nice to be
able to skip them when running the `check` task on the SQL module.
Introduce a new task `checkNoBwc` so one can use:
```
./gradlew -p x-pack/plugin/sql checkNoBwc
```
to skip them.

`my``identifier` = "some_value"
