[ML] inference only persist if there are stats (#54752) (#55121)
We needlessly send documents to be persisted. If there are no stats added, then we should not attempt to persist them.

Also, this PR fixes the race condition that caused issue:  https://github.com/elastic/elasticsearch/issues/54786

[7.x] [ML] Start gathering and storing inference stats (#53429) (#54738)
* [ML] Start gathering and storing inference stats (#53429)

This PR enables stats on inference to be gathered and stored in the `.ml-stats-*` indices.

Each node + model_id will have its own running stats document and these will later be summed together when returning _stats to the user.

`.ml-stats-*` is ILM managed (when possible). So, at any point the underlying index could change. This means that a stats document that is read in and then later updated will actually be a new doc in a new index. This complicates matters as this means that having a running knowledge of seq_no and primary_term is complicated and almost impossible. This is because we don't know the latest index name.

We should also strive for throughput, as this code sits in the middle of an ingest pipeline (or even a query).

Preserve parent task id for data frame analytics (#55046)
This change makes sure that all internal client requests spawned by the
data frame analytics persistent task executor and that use the end user
security credentials, have the parent task id assigned. The objective here
is to permit auditing (as well as tracking for debugging purposes) of all
the end-user requests executed on its behalf by persistent tasks.
Because data frame analytics taks already implements graceful shutdown
of child tasks, this change does not interfere with it by opting out of
the persistent task cancellation of child tasks.

Resolve SSO roles by pattern (#54777)
This changes a SamlServiceProvider to have a function that maps
from an "action-name" to set of role-names instead of a Map that does
so.

The on-disk representation of this mapping is a set of Java Regexp
Patterns, for which the first matching group is the role name.

For example "sso:(\w+)" would map any action that started with "sso:"
to the corresponding role name (e.g. "sso:superuser" -> "superuser").

Force stopping a failed job used to work but it

Rename MetaData to Metadata in all of the places (#54519)
This is a simple naming change PR, to fix the fact that "metadata" is a
single English word, and for too long we have not followed general
naming conventions for it. We are also not consistent about it, for
example, METADATA instead of META_DATA if we were trying to be
consistent with MetaData (although METADATA is correct when considered
in the context of "metadata"). This was a simple find and replace across
the code base, only taking a few minutes to fix this naming issue
forever.

Clean up how pipeline aggs check for multi-bucket (backport of #54161) (#54379)
Pipeline aggregations like `stats_bucket`, `sum_bucket`, and
`percentiles_bucket` only operate on buckets that have multiple buckets.
This adds support for those aggregations to `geo_distance`, `ip_range`,
`auto_date_histogram`, and `rare_terms`.

This all happened because we used a marker interface to mark compatible
aggs, `MultiBucketAggregationBuilder` and it was fairly easy to forget
to implement the interface.

This replaces the marker interface with an abstract method in
`AggregationBuilder`, `bucketCardinality` which makes you return `NONE`,
`ONE`, or `MANY`. The `bucket` aggregations can check for `MANY`. At
this point `ONE` and `NONE` amount to about the same thing, but I
suspect that'll be a useful distinction when validating bucket sorts.

Refactor AliasOrIndex abstraction. (#54394)
Backport of #53982

In order to prepare the `AliasOrIndex` abstraction for the introduction of data streams,
the abstraction needs to be made more flexible, because currently it really can be only
an alias or an index.

* Renamed `AliasOrIndex` to `IndexAbstraction`.
* Introduced a `IndexAbstraction.Type` enum to indicate what a `IndexAbstraction` instance is.
* Replaced the `isAlias()` method that returns a boolean with the `getType()` method that returns the new Type enum.
* Moved `getWriteIndex()` up from the `IndexAbstraction.Alias` to the `IndexAbstraction` interface.
* Moved `getAliasName()` up from the `IndexAbstraction.Alias` to the `IndexAbstraction` interface and renamed it to `getName()`.
* Removed unnecessary casting to `IndexAbstraction.Alias` by just checking the `getType()` method.

Invert license security disabled helper method (#54043) (#54239)
Xpack license state contains a helper method to determine whether
security is disabled due to license level defaults. Most code needs to
know whether security is enabled, not disabled, but this method exists
so that the security being explicitly disabled can be distinguished from
licence level defaulting to disabled. However, in the case that security
is explicitly disabled, the handlers in question are never registered,
so security is implicitly not disabled explicitly, and thus we can share
a single method to know whether licensing is enabled.

[ML] adds multi-class feature importance support (#53803) (#54024)
Adds multi-class feature importance calculation. 

Feature importance objects are now mapped as follows
(logistic) Regression:
```
{
   "feature_name": "feature_0",
   "importance": -1.3
}
```
Multi-class [class names are `foo`, `bar`, `baz`]
```
{ 
   “feature_name”: “feature_0”, 
   “importance”: 2.0, // sum(abs()) of class importances
   “foo”: 1.0, 
   “bar”: 0.5, 
   “baz”: -0.5 
},
```

For users to get the full benefit of aggregating and searching for feature importance, they should update their index mapping as follows (before turning this option on in their pipelines)
```
 "ml.inference.feature_importance": {
          "type": "nested",
          "dynamic": true,
          "properties": {
            "feature_name": {
              "type": "keyword"
            },
            "importance": {
              "type": "double"
            }
          }
        }
```
The mapping field name is as follows
`ml.<inference.target_field>.<inference.tag>.feature_importance`
if `inference.tag` is not provided in the processor definition, it is not part of the field path.
`inference.target_field` is defaulted to `ml.inference`.
//cc @lcawl ^ Where should we document this?

If this makes it in for 7.7, there shouldn't be any feature_importance at inference BWC worries as 7.7 is the first version to have it.
