JDK11 introduced some changes with the SSLEngine. A number of error
messages were changed. Additionally, there were some behavior changes
in regard to how the SSLEngine handles closes during the handshake
process. This commit updates our tests and SSLDriver to support these
changes.
All of the tests in PainlessDomainSplitIT have an awaitsfix, which
causes the build to fail since no tests are run. This adds an empty
test to get the build going again.

* Replace custom type names with _doc in REST examples.
* Avoid using two mapping types in the percolator docs.
* Rename doc -> _doc in the main repository README.
* Also replace some custom type names in the HLRC docs.
The security native stores follow a pattern where
`SecurityIndexManager#prepareIndexIfNeededThenExecute` wraps most calls
made for the security index. The reasoning behind this was to check if
the security index had been upgraded to the latest version in a
consistent manner. However, this has the potential side effect that a
read will trigger the creation of the security index or an updating of
its mappings, which can lead to issues such as failures due to put
mapping requests timing out even though we might have been able to read
from the index and get the data necessary.
This change introduces a new method, `checkIndexVersionThenExecute`,
that provides the consistent checking of the security index to make
sure it has been upgraded. That is the only check that this method
performs prior to running the passed in operation, which removes the
possible triggering of index creation and mapping updates for reads.
Additionally, areas where we do reads now check the availability of the
security index and can short circuit requests. Availability in this
context means that the index exists and all primaries are active.
This is the fixed version of #34246, which was reverted.

* Make accounting circuit breaker settings dynamic
These missed the original property making them dynamic. This fixes the issue so
these can now be set at any time.

We should be consistent here. We were already using the casing "Ccr" and
this is the preferred casing for Java class names. This commit adjusts
the names of some classes that were using the casing "CCR" to be "Ccr".
In the docs tests, we have pre-defined setups in the build.gradle file,
and we can also define test setup sections within the doc page
itself. Alas, these two are incompatible in that if you try to use a
pre-defined setup alongside a test setup section, the pre-defined setup
will be silently ignored. This commit enables pre-defined setup sections
to be used together with test setup sections. The ordering here is that
pre-defined setup sections will be executed first, followed by the test
setup section.
In some of our X-Pack REST tests we have to wait for pending tasks to
complete. We are now needing this functionality in ESRestTestCase for
the docs tests where we run against X-Pack features. This commit moves
the helper method that we have in X-Pack to ESRestTestCase, and removes
duplicate logic from waiting for rollup tasks to complete.
This commit switches to using a trial license in the docs tests that run
on the default distribution. This is needed so that docs tests can be
executed against non-basic features.
This change introduces stats per processors. Total, time, failed,
current are currently supported. All pipelines will now show all
top level processors that belong to it. Failure processors are not
displayed, however, the time taken to execute the failure chain is part
of the stats for the top level processor.
The processor name is the type of the processor, ordered as defined in
the pipeline. If a tag for the processor is found, then the tag is
appended to the type.
Pipeline processors will have the pipeline name appended to the name of
the name of the processors (before the tag if one exists). If more
then one pipeline is used to process the document, then each pipeline
will carry its own stats. The outer most pipeline will also include the
inner most pipeline stats.
Conditional processors will only included in the stats if the condition evaluates
to true.
After we bumped the JDK compiler minimum requirements to JDK 11, we
missed updating the contributing docs to point to JDK 11 instead of JDK
10. This commit fixes that.
Additionally, when we stopped requiring JDK 7 to run the reindex from
old tests, we did not update the contributing docs to reflect this. This
commit also fixes that.
With remote clusters taking on a larger role, we have make the
infrastructure more generic than being tied to cross-cluster search
(CCS). We want to refer to the remote clusters configuration in the
cross-cluster replication (CCR) docs. Yet, these docs are still tied to
CCS. This commit extracts the remote clusters docs from CCS (with some
wording changes to make them more general) so that we can refer to them
in the CCR docs.
Since #34288, we might hit deadlock if the FollowTask has more fetchers
than writers. This can happen in the following scenario:
Suppose the leader has two operations [seq#0, seq#1]; the FollowTask has
two fetchers and one writer.
1. The FollowTask issues two concurrent fetch requests: {from_seq_no: 0,
num_ops:1} and {from_seq_no: 1, num_ops:1} to read seq#0 and seq#1
respectively.
2. The second request which fetches seq#1 completes before, and then it
triggers a write request containing only seq#1.
3. The primary of a follower fails after it has replicated seq#1 to
replicas.
4. Since the old primary did not respond, the FollowTask issues another
write request containing seq#1 (resend the previous write request).
5. The new primary has seq#1 already; thus it won't replicate seq#1 to
replicas but will wait for the global checkpoint to advance at least
seq#1.
The problem is that the FollowTask has only one writer and that writer
is waiting for seq#0 which won't be delivered until the writer completed.
This PR proposes to replicate existing operations with the old primary
term (instead of the current term) on the follower. In particular, when
the following primary detects that it has processed an process already,
it will look up the term of an existing operation with the same seq_no
in the Lucene index, then rewrite that operation with the old term
before replicating it to the following replicas. This approach is
wait-free but requires soft-deletes on the follower.

Fixes#34418
The shard suggestion sort uses a different tie-break than the one that is used
to merge different shards responses. The former uses the internal document identifier
when scores are the same whereas the latter compares the surface form first.
Because of this discrepancy some suggestion outputs are linked to the wrong documents
because the merge sort reorders the shard suggestions differently. This change
fixes this bug by duplicating the Lucene collector in order to be able to apply the
same tiebreak strategy than the merge sort. This logic will be removed when
https://issues.apache.org/jira/browse/LUCENE-8529 is fixed.
Closes#34378
Today we rely on the LocalCheckpointTracker to ensure no duplicate when
enabling optimization using max_seq_no_of_updates. The problem is that
the LocalCheckpointTracker is not fully reloaded when opening an engine
with an out-of-order index commit. Suppose the starting commit has seq#0
and seq#2, then the current LocalCheckpointTracker would return "false"
when asking if seq#2 was processed before although seq#2 in the commit.
This change scans the existing sequence numbers in the starting commit,
then marks these as completed in the LocalCheckpointTracker to ensure
the consistent state between LocalCheckpointTracker and Lucene commit.
