Guess root cause support unwrap (#50525) (#50742)
ElasticsearchException.guessRootCauses would return wrapper exception if
inner exception was not an ElasticsearchException. Fixed to never return
wrapper exceptions.

At least following APIs change root_cause.0.type as a result:

_update with bad script
_index with bad pipeline

Add per-field metadata. (#50333)
This PR adds per-field metadata that can be set in the mappings and is later
returned by the field capabilities API. This metadata is completely opaque to
Elasticsearch but may be used by tools that index data in Elasticsearch to
communicate metadata about fields with tools that then search this data. A
typical example that has been requested in the past is the ability to attach
a unit to a numeric field.

In order to not bloat the cluster state, Elasticsearch requires that this
metadata be small:
 - keys can't be longer than 20 chars,
 - values can only be numbers or strings of no more than 50 chars - no inner
   arrays or objects,
 - the metadata can't have more than 5 keys in total.

Given that metadata is opaque to Elasticsearch, field capabilities don't try to
do anything smart when merging metadata about multiple indices, the union of
all field metadatas is returned.

Here is how the meta might look like in mappings:

```json
{
  "properties": {
    "latency": {
      "type": "long",
      "meta": {
        "unit": "ms"
      }
    }
  }
}
```

And then in the field capabilities response:

```json
{
  "latency": {
    "long": {
      "searchable": true,
      "aggreggatable": true,
      "meta": {
        "unit": [ "ms" ]
      }
    }
  }
}
```

When there are no conflicts, values are arrays of size 1, but when there are
conflicts, Elasticsearch includes all unique values in this array, without
giving ways to know which index has which metadata value:

```json
{
  "latency": {
    "long": {
      "searchable": true,
      "aggreggatable": true,
      "meta": {
        "unit": [ "ms", "ns" ]
      }
    }
  }
}
```

Teach ObjectParser a happy pattern (#50691) (#50710)
We *very* commonly have object with ctors like:
```
public Foo(String name)
```

And then declare a bunch of setters on the object. Every aggregation
works like this, for example. This change teaches `ObjectParser` how to
build these aggregations all on its own, without any help. This'll make
it much cleaner to parse aggs, and, probably, a bunch of other things.
It'll let us remove lots of wrapping. I've used this new power for the
`avg` aggregation just to prove that it works outside of a unit test.

Remove races in ProxyConnectionStrategyTests (#50620)
Currently, we use delayed address resolution in the proxy strategy tests
to allow tests to connect to different addresses. Unfortunately, this
has the potential to introduce races as the address is resolved each
connection attempt. The number of connection attempts can vary based on
when connections are opening and closing. This commit modifies the test
be allowing them to specifically control which address is used.

Declare remaining parsers `final` (#50571) (#50615)
We have about 800 `ObjectParsers` in Elasticsearch, about 700 of which
are final. This is *probably* the right way to declare them because in
practice we never mutate them after they are built. And we certainly
don't change the static reference. Anyway, this adds `final` to these
parsers.

I found the non-final parsers with this:
```
diff \
  <(find . -type f -name '*.java' -exec grep -iHe 'static.*PARSER\s*=' {} \+ | sort) \
  <(find . -type f -name '*.java' -exec grep -iHe 'static.*final.*PARSER\s*=' {} \+ | sort) \

Improve FutureUtils.get exception handling (#50339) (#50417)
FutureUtils.get() would unwrap ElasticsearchWrapperExceptions. This
is trappy, since nearly all usages of FutureUtils.get() expected only to
not have to deal with checked exceptions.

In particular, StepListener builds upon ListenableFuture which uses
FutureUtils.get to be informed about the exception passed to onFailure.
This had the bad consequence of masking away any exception that was an
ElasticsearchWrapperException like RemoteTransportException.
Specifically for recovery, this made CircuitBreakerExceptions happening
on the target node look like they originated from the source node.

The only usage that expected that behaviour was AdapterActionFuture.
The unwrap behaviour has been moved to that class.

Oleg 7539fbb30f Deprecate the 'local' parameter of /_cat/nodes (#50499)
The cat nodes API performs a `ClusterStateAction` then a `NodesInfoAction`.
Today it accepts the `?local` parameter and passes this to the
`ClusterStateAction` but this parameter has no effect on the `NodesInfoAction`.
This is surprising, because `GET _cat/nodes?local` looks like it might be a
completely local call but in fact it still depends on every node in the
cluster.

This commit deprecates the `?local` parameter on this API so that it can be
removed in 8.0.

Add remote info to the HLRC (#50483)
The additional change to the original PR (#49657), is that `org.elasticsearch.client.cluster.RemoteConnectionInfo` now parses the initial_connect_timeout field as a string instead of a TimeValue instance.

The reason that this is needed is because that the initial_connect_timeout field in the remote connection api is serialized for human consumption, but not for parsing purposes.
Therefore the HLRC can't parse it correctly (which caused test failures in CI, but not in the PR CI
:( ). The way this field is serialized needs to be changed in the remote connection api, but that is a breaking change. We should wait making this change until rest api versioning is introduced.

Nhat Nguyen 33204c2055 Use peer recovery retention leases for indices without soft-deletes (#50351)
Today, the replica allocator uses peer recovery retention leases to
select the best-matched copies when allocating replicas of indices with
soft-deletes. We can employ this mechanism for indices without
soft-deletes because the retaining sequence number of a PRRL is the
persisted global checkpoint (plus one) of that copy. If the primary and
replica have the same retaining sequence number, then we should be able
to perform a noop recovery. The reason is that we must be retaining
translog up to the local checkpoint of the safe commit, which is at most
the global checkpoint of either copy). The only limitation is that we
might not cancel ongoing file-based recoveries with PRRLs for noop
recoveries. We can't make the translog retention policy comply with
PRRLs. We also have this problem with soft-deletes if a PRRL is about to
expire.

Make the TransportRolloverAction execute in one cluster state update (#50388) (#50442)
This commit makes the TransportRolloverAction more resilient, by having it execute
only one cluster state update that creates the new (rollover index), rolls over
the alias from the source to the target index and set the RolloverInfo on the

updates, which would've seen the user manually intervene if, say, the alias
rollover cluster state update (second in the chain) failed but the creation of
the rollover index (first in the chain) update succeeded

Optimize composite aggregation based on index sorting (#48399) (#50272)
Co-authored-by: Daniel Huang <danielhuang@tencent.com>

This is a spinoff of #48130 that generalizes the proposal to allow early termination with the composite aggregation when leading sources match a prefix or the entire index sort specification.
In such case the composite aggregation can use the index sort natural order to early terminate the collection when it reaches a composite key that is greater than the bottom of the queue.
The optimization is also applicable when a query other than match_all is provided. However the optimization is deactivated for sources that match the index sort in the following cases:
  * Multi-valued source, in such case early termination is not possible.
  * missing_bucket is set to true

Extract a create index method that only manipulates the ClusterState (#50240) (#50328)
* Extract IndexCreationTask execute into applyCreateIndexRequest

This is the first step in preparation for separating the index creation into a few
steps that only deal with the cluster state mutation and removing the IndexCreationTask
altogether.

* Split applyCreateIndexRequest

This breaks down the logic in applyCreateIndexRequest into multiple
steps that will hopefully make the service more readable and unit testable.
The service creation process now goes through a few well defined steps,
namely find the templates that possibly match the new index, parse the
requested and template matching mappings, process the index and template
matching settings, validate the wait for active shards request and
create the `IndexService`, update the mappings in the `MapperService` (which
is grouped together with creating the sort order for validation purposes),
validate the requested and templated matching aliases and finally update
the `ClusterState` to reflect the requested changes.

This also removes the `IndexCreationTask` as it was a shallow
indirection and migrates the tests from `IndexCreationTaskTests` to
`MetaDataCreateIndexServiceTests` (making them "real" unit tests
operating on the `ClusterState` rather than mocks).

* Add more unit tests.

* Add IT to verify we cleanup in case of failure
