Remove Mostly Redundant Deleting in FsBlobContainer (#60117) (#60195)
In almost all cases we write uuid named files via this method.
Preemptively deleting just wastes IO ops, we can delete after a write failed
and retry the write to cover the few cases where we actually do an overwrite.

[7.x][ML] DFA result processor should only skip rows and model chunks on cancel (#60113) (#60193)
When the job is force-closed or shutting down due to a fatal error we clean
up all cancellable job operations. This includes cancelling the results processor.
However, this means that we might not persist objects that are written from the
process like stats, memory usage, etc.

In hindsight, we do not gain from cancelling the results processor in its
entirety. It makes more sense to skip row results and model chunks but keep
stats and instrumentation about the job as the latter may contain useful information
to understand what happened to the job.

Don't require separate privilege for internal detail of put pipeline (#60190)
Putting an ingest pipeline used to require that the user calling
it had permission to get nodes info as well as permission to
manage ingest.  This was due to an internal implementaton detail
that was not visible to the end user.

This change alters the behaviour so that a user with the
manage_pipeline cluster privilege can put an ingest pipeline
regardless of whether they have the separate privilege to get
nodes info.  The internal implementation detail now runs as
the internal _xpack user when security is enabled.

Fix Test Failure in testConcurrentlyChangeRepositoryContentsInBwCMode (#60095)
There is a very unlikely but possible test failure in this test.
The `SnapshotsService` continues iterating over queued operations after
resolving the transport listener. This can lead to a situation where the moved
repository data is not picked up when running the delete (even though we
have the concurrent modifications BwC mode activated) concurrently.

I fixed this in the test so that the test still verifies that this setting works.
Technically speaking, one could add logic to the way we queue and execute repo operations
to address this special case. Since this case only comes about with the concurrent modifications
setting enabled (and the setting is gone in master already) I don't really see a reason to improve
the logic here since we should always fail queued up repo operations on concurrent modification for
safety reasons.

David Turner bf7e53a91e Remove node-level canAllocate override (#59389)
Today there is a node-level `canAllocate` override which the balancer
uses to ignore certain nodes to which it is certain no more shards can
be allocated. In fact this override only ignores nodes which have hit
the rarely-used `cluster.routing.allocation.total_shards_per_node`
limit, so this optimization doesn't have a meaningful impact on real
clusters.

This commit removes this unnecessary fast path from the balancer, and
also removes all the machinery needed to support it.

Optimize some Spots around Closing Resources (#60049) (#60096)
The single element `close` calls go through a very inefficient path that includes creating
a one element list.
`releaseOnce` is only with a single non-null input in production in two spots so no need for
varargs and any complexity here.
`ReleasableBytesStreamOutput` does not require any `releaseOnce` wrapping because we already have
that kind of logic implemented in `org.elasticsearch.common.util.AbstractArray` (which we were
wrapping here) already.

Formalize and Streamline Buffer Sizes used by Repositories (#59771) (#60051)
Due to complicated access checks (reads and writes execute in their own access context) on some repositories (GCS, Azure, HDFS), using a hard coded buffer size of 4k for restores was needlessly inefficient.
By the same token, the use of stream copying with the default 8k buffer size  for blob writes was inefficient as well.

We also had dedicated, undocumented buffer size settings for HDFS and FS repositories. For these two we would use a 100k buffer by default. We did not have such a setting for e.g. GCS though, which would only use an 8k read buffer which is needlessly small for reading from a raw `URLConnection`.

This commit adds an undocumented setting that sets the default buffer size to `128k` for all repositories. It removes wasteful allocation of such a large buffer for small writes and reads in case of HDFS and FS repositories (i.e. still using the smaller buffer to write metadata) but uses a large buffer for doing restores and uploading segment blobs.

This should speed up Azure and GCS restores and snapshots in a non-trivial way as well as save some memory when reading small blobs on FS and HFDS repositories.

Thread safe clean up of LocalNodeModeListeners (#60007)
This commit continues on the work in #59801 and makes other
implementors of the LocalNodeMasterListener interface thread safe in
that they will no longer allow the callbacks to run on different
threads and possibly race each other. This also helps address other
issues where these events could be queued to wait for execution while
the service keeps moving forward thinking it is the master even when
that is not the case.

In order to accomplish this, the LocalNodeMasterListener no longer has
the executorName() method to prevent future uses that could encounter
this surprising behavior.

Each use was inspected and if the class was also a
ClusterStateListener, the implementation of LocalNodeMasterListener
was removed in favor of a single listener that combined the logic. A
single listener is used and there is currently no guarantee on execution
order between ClusterStateListeners and LocalNodeMasterListeners,
so a future change there could cause undesired consequences. For other
classes, the implementations of the callbacks were inspected and if the
operations were lightweight, the overriden executorName method was
removed to use the default, which runs on the same thread.

[7.x][ML] Include same fields during test inference as in training (#… (#60034)
In #58877, when we switched test inference on java, we just
use the doc's `_source` as features. However, this could be
missing out on features that were used during training,
e.g. alias fields, etc.

This commit addresses this by extracting fields to use as
features during inference the same way they are extracted
in `DataFrameDataExtractor` when they are used for training.

Fix BwC Snapshot INIT Path (#60006)
There were two subtle bugs here from backporting #56911 to 7.x.

1. We passed `null` for the `shards` map which isn't nullable any longer
when creating `SnapshotsInProgress.Entry`, fixed by just passing an empty map
like the `null` handling did in the past.
2. The removal of a failed `INIT` state snapshot from the cluster state tried
removing it from the finalization loop (the set of repository names that are
currently finalizing). This will trip an assertion since the snapshot failed
before its repository was put into the set. I made the logic ignore the set
in case we remove a failed `INIT` state snapshot to restore the old logic to
exactly as it was before the concurrent snapshots backport to be on the safe
side here.

Also, added tests that explicitly call the old code paths because as can be seen
from initially missing this, the BwC tests will only run in the configuration new
version master, old version nodes ever so often and having a deterministic test
for the old state machine seems the safest bet here.
