Document level security was depending on the shared
"BitsetFilterCache" which (by design) never expires its entries.
However, when using DLS queries - particularly templated ones - the
number (and memory usage) of generated bitsets can be significant.
This change introduces a new cache specifically for BitSets used in
DLS queries, that has memory usage constraints and access time expiry.
The whole cache is automatically cleared if the role cache is cleared.
Individual bitsets are cleared when the corresponding lucene index
reader is closed.
The cache defaults to 50MB, and entries expire if unused for 7 days.

This change fixes the name of the index_prefix sub field when the `index_prefix`
option is set on a text field that is nested under an object or a multi-field.
We don't use the full path of the parent field to set the index_prefix field name
so the field is registered under the wrong name. This doesn't break queries since
we always retrieve the prefix field through its parent field but this breaks other
APIs like _field_caps which tries to find the parent of the `index_prefix` field
in the mapping but fails.
Closes#43741
If an item in the bulk request fails, that could be for a variety of
reasons - it may be that the underlying behaviour of security has
changed, or it may just be a transient failure during testing.
Simply asserting a `true`/`false` value produces failure messages that
are difficult to diagnose and debug. Using hamcert (`assertThat`) will
make it easier to understand the causes of failures in this test.

This commit allows bulk upserts to correctly read the default pipeline
for the concrete index that belongs to an alias.
Bulk upserts are modeled differently from normal index requests such that
the index request is a request inside of the update request. The update
request (outer) contains the index or alias name is not part of the (inner)
index request. This commit adds a secondary check against the update request
(outer) if the index request (inner) does not find an alias.
Typically, dense vectors of both documents and queries must have the same
number of dimensions. Different number of dimensions among documents
or query vector indicate an error. This PR enforces that all vectors
for the same field have the same number of dimensions. It also enforces
that query vectors have the same number of dimensions.

* fix org.elasticsearch.xpack.watcher.test.integration.RejectedExecutionTests (#41777)
This commit un-mutes org.elasticsearch.xpack.watcher.test.integration.RejectedExecutionTests
which was failing intermittently due to a logic bug. It is not possible to use the real
Watcher scheduler (which is needed for this test) and reliabliby count the .triggered-watches
since current count of documents in the .triggered-watches index is based on the timing of the
scheduler and the ability to delete based on the Watcher and Write thread pools.
This commit simply removes the .triggered-watch check and relies soley on the .watcher-history
index as an indication that operations that can occur when the Watcher threadpool is rejecting.

* fix unlikely bug that can prevent Watcher from restarting (#42030)
The bug fixed here is unlikely to happen. It requires ES to be started with
ILM disabled, Watcher enabled, and Watcher explicitly stopped and restarted.
Due to template validation Watcher does not fully start and can result in a
partially started state. This is an unlikely scenerio outside of the testing
framework.
Note - this bug was introduced while the test that would have caught it was
muted. The test remains muted since the underlying cuase of the random failures
has not been identified. When this test is un-muted it will now work.
Adds the monitor_data_frame_transforms and
manage_data_frame_transforms cluster privileges to
the high level rest client.
The ALL_ARRAY variable is only used in randomized
tests at the within the Elasticsearch code, so it's
not a major problem that these cluster privileges
weren't added from the start. But since ALL_ARRAY
is public HLRC users may be using it to find out
which cluster privileges exist, so it's best that
it contains them all.
Currently the repsonse of the "_reload_search_analyzer" endpoint contains the
index names and nodeIds of indices were analyzers reloading was triggered. This
change add the names of the search-time analyzers that were reloaded.

With Lucene rollback (#33473), we should never have more than one
primary term for each sequence number. Therefore we don't have to sort
by the primary term when reading soft-deletes.
This adds a new cluster privilege for manage_api_key. Users with this
privilege are able to create new API keys (as a child of their own
user identity) and may also get and invalidate any/all API keys
(including those owned by other users).

A few places in the documentation had mentioned 6.7 as the version to
upgrade from, when doing an upgrade to 7.0. While this is technically
possible, this commit will replace all those mentions to 6.8, as this is
the latest version with the latest bugfixes, deprecation checks and
ugprade assistant features - which should be the one used for upgrades.

The `RoutingService` has a confusing name, since it doesn't really have
anything to do with routing. Its responsibility is submitting reroute commands
to the master.
This commit renames this class to `BatchedRerouteService`, and extracts the
`RerouteService` interface to avoid passing `BiConsumer`s everywhere. It also
removes that `BatchedRerouteService extends AbstractLifecycleComponent` since
this service has no meaningful lifecycle. Finally, it introduces a small
wrapper class to allow for lazy initialization to deal with the dependency loop
when constructing a `Node`.
This is an odd backport of #41774
UserRoleMapper.UserData is constructed by each realm and it is used to
"match" role mapping expressions that eventually supply the role names
of the principal.
This PR filters out `null` collection values (lists and maps), for the groups
and metadata, which get to take part in the role mapping, in preparation
for using Java 9 collection APIs. It filters them as soon as possible, during
the construction.
This adds a `rare_terms` aggregation. It is an aggregation designed
to identify the long-tail of keywords, e.g. terms that are "rare" or
have low doc counts.
This aggregation is designed to be more memory efficient than the
alternative, which is setting a terms aggregation to size: LONG_MAX
(or worse, ordering a terms agg by count ascending, which has
unbounded error).
This aggregation works by maintaining a map of terms that have
been seen. A counter associated with each value is incremented
when we see the term again. If the counter surpasses a predefined
threshold, the term is removed from the map and inserted into a cuckoo
filter. If a future term is found in the cuckoo filter we assume it
was previously removed from the map and is "common".
The map keys are the "rare" terms after collection is done.
Following the removal of the `unzip` package from the Elasticsearch

This commit merges the `object-fields` feature branch. The new 'flattened
