We changed the way realm settings are defined, and this affects custom
realms in SecurityExtensions. This change adds those details to the
breaking changes docs.

* [DOCS] ILM API Ref edits
* [DOCS] Fixed endpoint for DELETE policy.
* [DOCS] Removed comparison to setting index.lifecycle.name to null.
* [DOCS] Fixed xrefs to explain API.
Change `nullable()` logic of AND and OR to false since in the Optimizer
we cannot fold to null as we might be handling and expression in the
SELECT clause.
Introduce folding of null for AND and OR expressions in PruneFilter()
since we now know that we are in HAVING or WHERE clause and we
can fold `null` to `false`

This is related to #34483. It introduces a namespaced setting for
compression that allows users to configure compression on a per remote
cluster basis. The transport.tcp.compress remains as a fallback
setting. If transport.tcp.compress is set to true, then all requests
and responses are compressed. If it is set to false, only requests to
clusters based on the cluster.remote.cluster_name.transport.compress
setting are compressed. However, after this change regardless of any
local settings, responses will be compressed if the request that is
received was compressed.
Today our OS information returned in node stats only returns a
high-level name of the OS (e.g., "Linux"). Yet, for some uses this is
too high-level and knowing at a finer level of granularity the
underlying OS can be useful. This commit extracts the pretty name on
Linux from /etc/os-release. This pretty name usually includes the Linux
vendor and the Linux vendor version number (e.g., Fedora 28).
This follows #33552 , when the `_authenticate` API added a new
`User` object for the API's response. This changes the `put_user`
API to also employ a `User` object in the request.
The User object changed slightly.
A bug with put_user only putting/updating enabled (but not disabled)
users has been fixed.
Currently we introduced a hard limit of 1024 to the number of fields a query can
be expanded to in #26541. Instead of using a hard limit, we should make this
configurable. This change removes the hard limit check and uses the existing
`max_clause_count` setting instead.
Closes#34778
Currently when aggregating on an unmapped date field (e.g. using a
date_histogram) we don't preserve the aggregations `format` setting but instead
use the default format. This can lead to loosing the aggregations `format` when
aggregating over several indices where some of them contain unmapped date fields
and are encountered first in the reduce phase.
Related to #31760
Today the `composite` aggregation throws an error if a source targets an
unmapped field and `missing_bucket` is set to false. Documents without a
value for a source cannot produce any bucket if `missing_bucket` is not
activated so the error is a shortcut to say that the response will be empty.
However this is not consistent with the `terms` aggregation which accepts
unmapped field by default even if the response is also guaranteed to be empty.
This commit removes this restriction, if a source contains an unmapped field
we now return an empty response (no buckets).
Closes#35317
The current implementation of asyncBlockOperations() can be used to
execute some code once all indexing operations permits have been acquired,
then releases all permits immediately after the code execution. This
immediate release is not suitable for treatments that need to keep all
permits over multiple execution steps.
This commit adds a new asyncBlockOperations() that exposes a Releasable,
making it possible to acquire all permits and only release them all
when needed by closing the Releasable. The existing blockOperations()
method has been modified to delegate permit acquisition/releasing to this new
method.

Extend High Level Rest Client Reindex API to support requests with
wait_for_completion=false. This method will return a TaskSubmissionResult with task identifier as string and results can be queried with Task API

If the underlying mount point for the JNA temporary directory is mounted
noexec on Linux, then the JVM will not be able to map the native code in
as executable. This will prevent JNA from executing and will prevent
Elasticsearch from being able to execute some functions that rely on
native code (e.g., memory locking, and installing system call
filters). We do not want to get into the business of catching exceptions
and parsing messages towards this because these exception messages can
change on us. We also do not want to jump through a lot of hoops to
check the underlying mount point for noexec. Instead, we will rely on
documentation to address this problem. This commit adds to the important
system configuration section of the docs that the JNA temporary
directory is not on a mount point with the noexec mount option.
Adjust list of dynamic index settings that should be replicated
and added a test that verifies whether builtin dynamic index settings
are classified as replicated or non replicated (whitelisted).
This commit uses the index settings version so that a follower can
replicate index settings changes as needed from the leader.

There is no longer a concept of non-global "realm settings". All realm
settings should be loaded from the node's settings using standard
Setting classes.
This change renames the "globalSettings" field and method to simply be
"settings".
The file realm has not supported custom filenames/locations since at
least 5.0, but this test still tried to configure them.
Remove all configuration of file locations, and cleaned up a few other
warnings and deprecations
The lookup vars under params (namely _fields and _source) were
inadvertently removed when scoring scripts were converted to using
script contexts. This commit adds them back, along with deprecation
warnings for those that should not be used.

The change here is to throw an `AssertionError` instead of `break;` to
allow the `assertBusy()` to continue to busy wait until the desired
state is reached.

Since it's still possible to shrink an index when replicas are unassigned, we
should not check that all copies are available when performing the shrink, since
we set the allocation requirement for a single node.
Resolves#35321
A CCR test failure shows that the approach in #34474 is flawed.
Restoring the LocalCheckpointTracker from an index commit can cause both
FollowingEngine and InternalEngine to incorrectly ignore some deletes.
Here is a small scenario illustrating the problem:
1. Delete doc with seq=1 => engine will add a delete tombstone to Lucene
2. Flush a commit consisting of only the delete tombstone
3. Index doc with seq=0 => engine will add that doc to Lucene but soft-deleted
4. Restart an engine with the commit (step 2); the engine will fill its
LocalCheckpointTracker with the delete tombstone in the commit
5. Replay the local translog in reverse order: index#0 then delete#1
6. When process index#0, an engine will add it into Lucene as a live doc
and advance the local checkpoint to 1 (seq#1 was restored from the
commit - step 4).
7. When process delete#1, an engine will skip it because seq_no=1 is
less than or equal to the local checkpoint.
We should have zero document after recovering from translog, but here we
have one.
Since all operations after the local checkpoint of the safe commit are
retained, we should find them if the look-up considers also soft-deleted
documents. This PR fills the disparity between the version map and the
local checkpoint tracker by taking soft-deleted documents into account
while resolving strategy for engine operations.

* [ILM] Check shard and relocation status in AllocationRoutedStep
This is a follow-up from #35161 where we now check for started and relocating
state in `AllocationRoutedStep`.
Resolves#35258
Today when a percolator query contains a date range then the query
analyzer extracts that range, so that at search time the `percolate` query
can exclude percolator queries efficiently that are never going to match.
The problem is that if 'now' is used it is evaluated at index time.
So the idea is to rewrite date ranges with 'now' to a match all query,
so that the query analyzer can't extract it and the `percolate` query
is then able to evaluate 'now' at query time.
This change adds a `frozen` engine that allows lazily open a directory reader
on a read-only shard. The engine wraps general purpose searchers in a LazyDirectoryReader
that also allows to release and reset the underlying index readers after any and before
secondary search phases.

* cannot contain a `,`
* can be encoded in UTF-8

Adds basic rolling upgrade tests to check that lifecycles are still recognizable between rolling cluster upgrades and managed indices stay managed.
This is a placeholder for discussing types of checks so they are ready once we backported
This is a re-boot of the previous PR against index-lifecycle that needed to be
reverted due to CI bwc issues. #32828
