Allow TokenFilterFactories to rewrite themselves against their preceding chain (#33702)
We currently special-case SynonymFilterFactory and SynonymGraphFilterFactory, which need to 
know their predecessors in the analysis chain in order to correctly analyze their synonym lists. This
special-casing doesn't work with Referring filter factories, such as the Multiplexer or Conditional
filters. We also have a number of filters (eg the Multiplexer) that will break synonyms when they
appear before them in a chain, because they produce multiple tokens at the same position.

This commit adds two methods to the TokenFilterFactory interface.

* `getChainAwareTokenFilterFactory()` allows a filter factory to rewrite itself against its preceding
  filter chain, or to resolve references to other filters. It replaces `ReferringFilterFactory` and
  `CustomAnalyzerProvider.checkAndApplySynonymFilter`, and by default returns `this`.
* `getSynonymFilter()` defines whether or not a filter should be applied when building a synonym
  list `Analyzer`. By default it returns `true`.

Fixes #33609

[Tests] Nudge wait time in RemoteClusterServiceTests (#33853)
This test occasionally fails in `testCollectSearchShards` waiting on what seems
to be a search request to a remote cluster for one second. Given that the test
fails here very rarely I suspect maybe one second is very rarely not enough so
we could fix it by increasing the max wait time slightly.

Closes #33852

Move DocsStats into Engine (#33835)
By moving DocStats into the engine we can easily cache the stats for
read-only engines if necessary. It also moves the responsibility out of IndexShard
which has quiet some complexity already.

Use the global doc id to generate a random score (#33599)
This commit changes the random_score function to use the global docID of the document
rather than the segment docID to generate random scores. As a result documents that have
the same segment docID within the shard will generate different scores.

Add minimal sanity checks to custom/scripted similarities. (#33564)
Add minimal sanity checks to custom/scripted similarities.

Lucene 8 introduced more constraints on similarities, in particular:
 - scores must not be negative,
 - scores must not decrease when term freq increases,
 - scores must not increase when norm (interpreted as an unsigned long)
   increases.

We can't check every single case, but could at least run some sanity checks.

Profiler: Don’t profile NEXTDOC for ConstantScoreQuery. (#33196)
* Profiler: Don’t profile NEXTDOC for ConstantScoreQuery.

A ConstantScore query will return the iterator of its inner query.
However, when profiling, the constant score query is wrapped separately
from its inner query, which distorts the times emitted by the profiler.
Return the iterator directly in such a case.

New plugin - Annotated_text field type (#30364)
New plugin for annotated_text field type.
Largely a copy of `text` field type but adds ability to include markdown-like syntax in the text.
The “AnnotatedText” class parses text+markup and converts into plain text and AnnotationTokens.
The annotation token values are injected unchanged alongside the regular text tokens to provide a
form of additional indexed overlay useful in positional searches and highlighting.
Annotated_text fields do not support fielddata as we want to phase this out.
Also includes a new "annotated" highlighter type that retains annotations and merges in search
hits as additional annotation markup.

Make custom index metadata completely immutable (#33735)
Currently `IndexMetadata#getCustomData(...)` wraps the custom metadata
in an unmodifiable map, but in case there is no entry for the specified
key then a NPE is thrown by Collections.unmodifiableMap(...). This is not
ideal in case callers like to throw an exception with a specific message.
(like in the case for ccr to indicate that the follow index was not created
by the create_and_follow api and therefor incompatible as follow index)

I think making `DiffableStringMap` itself immutable is better then just wrapping
custom metadata with `Collections.unmodifiableMap(...)` in all methods that access it.

Also removed the `equals()`, `hashcode()` and to `toString()` methods of
`DiffableStringMap`, because `AbstractMap` already implements these methods.

Scripting: Rework joda time backcompat (#33486)
This commit switches the joda time backcompat in scripting to use
augmentation over ZonedDateTime. The augmentation methods provide
compatibility with the missing methods between joda's DateTime and
java's ZonedDateTime. Due to getDayOfWeek returning an enum in the java
API, ZonedDateTime is wrapped so that the method can return int like the
joda time does. The java time api version is renamed to
getDayOfWeekEnum, which will be kept through 7.x for compatibility while
users switch back to getDayOfWeek once joda compatibility is removed.

Only notify ready global checkpoint listeners (#33690)
When we add a global checkpoint listener, it is also carries along with
it a value that it thinks is the current global checkpoint. This value
can be above the actual global checkpoint on a shard if the listener
knows the global checkpoint from another shard copy (e.g., the primary),
and the current shard copy is lagging behind. Today we notify the
listener whenever the global checkpoint advances, regardless if it goes
above the current global checkpoint known to the listener. This commit
reworks this implementation. Rather than thinking of the value
associated with the listener as the current global checkpoint known to
the listener, we think of it as the value that the listener is waiting
for the global checkpoint to advance to (inclusive). Now instead of
notifying all waiting listeners when the global checkpoint advances, we
only notify those that are waiting for a value not larger than the
actual global checkpoint that we advanced to.

Core: Add DateFormatter interface for java time parsing (#33467)
The existing approach used date formatters when a format based string
like `date_time||epoch_millis` was used, instead of the custom code.

In order to properly solve this, a new interface called
`DateFormatter` has been added, which now can be implemented for custom
formatters. Currently there are two implementations, one using java time
and one doing the epoch_millis formatter, which simply parses a number
and then converts it to a date in UTC timezone.

The DateFormatter interface now also has a method to retrieve the name
of the formatter pattern, which is needed for mapping changes anyway.

The existing `CompoundDateTimeFormatter` class has been removed, the
name was not really nice anyway.

One more minor change is the fact, that the new java time using
FormatDateFormatter does not try to parse the date with its printer
implementation first (which might be a strict one and fail), but a
printer can now be specified in addition. This saves one potential
failure/exception when parsing less strict dates.

If only a printer is specified, the printer will also be used as a
parser.

Use file-based discovery not MockUncasedHostsProvider (#33554)
Today we use a special unicast hosts provider, the `MockUncasedHostsProvider`,

Add `_source`-only snapshot repository (#32844)
This change adds a `_source` only snapshot repository that allows to wrap
any existing repository as a _backend_ to snapshot only the `_source` part
including live docs markers. Snapshots taken with the `source` repository
won't include any indices,  doc-values or points. The snapshot will be reduced in size and
functionality such that it requires full re-indexing after it's successfully restored.

The restore process will copy the `_source` data locally starts a special shard and engine
to allow `match_all` scrolls and searches. Any other query, or get call will fail with and unsupported operation exception.  The restored index is also marked as read-only.

This feature aims mainly for disaster recovery use-cases where snapshot size is
a concern or where time to restore is less of an issue.

**NOTE**: The snapshot produced by this repository is still a valid lucene index. This change doesn't allow for any longer retention policies which is out of scope for this change.

Enable global checkpoint listeners to timeout (#33620)
In cross-cluster replication, we will use global checkpoint listeners to
long poll for updates to a shard. However, we do not want these polls to
wait indefinitely as it could be difficult to discern if the listener is
still waiting for updates versus something has gone horribly wrong and
cross-cluster replication is stuck. Instead, we want these listeners to
timeout after some period (for example, one minute) so that they are
notified and we can update status on the following side that
cross-cluster replication is still active. After this, we will
immediately enter back into a poll mode.

To do this, we need the ability to associate a timeout with a global
checkpoint listener. This commit adds this capability.

on cluster update settings requests. This commit only focuses on cluster
settings, index settings can build on this infrastructure in a
follow-up.

Include fallback settings when checking dependencies (#33522)
Today when checking settings dependencies, we do not check if fallback
settings are present. This means, for example, that if
cluster.remote.*.seeds falls back to search.remote.*.seeds, and
cluster.remote.*.skip_unavailable and search.remote.*.skip_unavailable
depend on cluster.remote.*.seeds, and we have set search.remote.*.seeds
and search.remote.*.skip_unavailable, then validation will fail because
it is expected that cluster.ermote.*.seeds is set here. This commit
addresses this by also checking fallback settings when validating
dependencies. To do this, we adjust the settings exist method to also
check for fallback settings, a case that it was not handling previously.

Logging: Configure the node name when we have it (#32983)
Change the logging infrastructure to handle when the node name isn't
available in `elasticsearch.yml`. In that case the node name is not
available until long after logging is configured. The biggest change is
that the node name logging no longer fixed at pattern build time.
Instead it is read from a `SetOnce` on every print. If it is unset it is
printed as `unknown` so we have something that fits in the pattern.
On normal startup we don't log anything until the node name is available
so we never see the `unknown`s.

TEST: Ensure merge triggered in _source retention test (#33487)
We invoke force merge twice in the test to verify that recovery sources

checkpoint equals to the local checkpoint in the first force-merge, the
second force-merge will be a noop because all deleted docs are expunged
in the first merge already. We need to flush a new segment to make merge
happen so we can verify that all recovery sources are pruned.

Fix IndexMetaData loads after rollover (#33394)
When we rollover and index we write the conditions of the rollover that
the old index met into the old index. Loading this index metadata
requires a working `NamedXContentRegistry` that has been populated with
parsers from the rollover infrastructure. We had a few loads that didn't
use a working `NamedXContentRegistry` and so would fail if they ever
encountered an index that had been rolled over. Here are the locations
of the loads and how I fixed them:

* IndexFolderUpgrader - removed entirely. It existed to support opening
indices made in Elasticsearch 2.x. Since we only need this change as far
back as 6.4.1 which will supports reading from indices created as far
back as 5.0.0 we should be good here.
* TransportNodesListGatewayStartedShards - wired the
`NamedXContentRegistry` into place.
* TransportNodesListShardStoreMetaData - wired the
`NamedXContentRegistry` into place.
* OldIndexUtils - removed entirely. It existed to support the zip based
index backwards compatibility tests which we've since replaced with code
that actually runs old versions of Elasticsearch.

In addition to fixing the actual problem I added full cluster restart
integration tests for rollover which would have caught this problem and
I added an extra assertion to IndexMetaData's deserialization code which
will trip if we try to deserialize and index's metadata without a fully
formed `NamedXContentRegistry`. It won't catch if use the *wrong*
`NamedXContentRegistry` but it is better than nothing.

[CCR] Added auto follow patterns feature (#33118)
Auto Following Patterns is a cross cluster replication feature that
keeps track whether in the leader cluster indices are being created with
names that match with a specific pattern and if so automatically let
the follower cluster follow these newly created indices.

This change adds an `AutoFollowCoordinator` component that is only active
on the elected master node. Periodically this component checks the
 the cluster state of remote clusters if there new leader indices that
match with configured auto follow patterns that have been defined in
`AutoFollowMetadata` custom metadata.

This change also adds two new APIs to manage auto follow patterns. A put
auto follow pattern api:

```
PUT /_ccr/_autofollow/{{remote_cluster}}
{
   "leader_index_pattern": ["logs-*", ...],
   "follow_index_pattern": "{{leader_index}}-copy",
   "max_concurrent_read_batches": 2
   ... // other optional parameters
}
```

and delete auto follow pattern api:

```
DELETE /_ccr/_autofollow/{{remote_cluster_alias}}
```

The auto follow patterns are directly tied to the remote cluster aliases
configured in the follow cluster.

Introduce `TransportLogger` for common logging (#32725)
Historically we have had a ESLoggingHandler in the netty module that
logs low-level connection operations. This class just extends the netty
logging handler with some (broken) message deserialization. This commit
fixes this message serialization and moves the class to server.

This new logger logs inbound and outbound messages. Eventually, we
should move other event logging to this class (connect, close, flush).
That way we will have consistent logging regards of which transport is
loaded.

Resolves #27306 on master. Older branches will need a different fix.

Don't count metadata fields towards index.mapping.total_fields.limit (#33386)
The maximum number of fields per index is limited to 1000 by default by the
`index.mapping.total_fields.limit` setting to prevent accidental mapping
explosions due to too many fields. Currently all metadata fields also count
towards this limit, which can lead to some confusion when using lower limits.
It is not obvious for users that they cannot actually add as many fields as
are specified by the limit in this case.

This change takes the number of metadata fields out of the field count that we
check against the field limit. It also adds tests that check that we can add
fields up to the specified limit, but throw an exception for any additional field added.

Introduce private settings (#33327)
This commit introduces the formal notion of a private setting. This
enables us to register some settings that we had previously not
registered as fully-fledged settings to avoid them being exposed via
APIs such as the create index API. For example, we had hacks in the
codebase to allow index.version.created to be passed around inside of
settings objects, but was not registered as a setting so that if a user
tried to use the setting on any API then they would get an
exception. This prevented users from setting index.version.created on
index creation, or updating it via the index settings API. By
introducing private settings, we can continue to reject these attempts,
yet now we can represent these settings as actual settings. In this
change, we register index.version.created as an actual setting. We do
not cutover all settings that we had been treating as private in this
pull request, it is already quite large due to moving some tests around
to account for the fact that some tests need to be able to set the
index.version.created. This can be done in a follow-up change.

Igor Motov 001b78f704 Replace IndexMetaData.Custom with Map-based custom metadata (#32749)
This PR removes the deprecated `Custom` class in `IndexMetaData`, in favor
of a `Map<String, DiffableStringMap>` that is used to store custom index
metadata. As part of this, there is now no way to set this metadata in a
template or create index request (since it's only set by plugins, or dedicated
REST endpoints).

The `Map<String, DiffableStringMap>` is intended to be a namespaced `Map<String,
String>` (`DiffableStringMap` implements `Map<String, String>`, so the signature
is more like `Map<String, Map<String, String>>`). This is so we can do things
like:

``` java
Map<String, String> ccrMeta = indexMetaData.getCustom("ccr");
```

And then have complete control over the metadata. This also means any
plugin/feature that uses this has to manage its own BWC, as the map is just
serialized as a map. It also means that if metadata is put in the map that isn't
used (for instance, if a plugin were removed), it causes no failures the way
an unregistered `Setting` would.

The reason I use a custom `DiffableStringMap` here rather than a plain
`Map<String, String>` is so the map can be diffed with previous cluster state
updates for serialization.

Remove usage of `index.shrink.source.*` in 7.x (#33271)
We cut over to `index.resize.source.*` but still have these constants
being public in `IndexMetaData`. Those Settings and constants are not needed
in 7.x while we still need to keep the keys known to private settings since
they might be part of the index settings of old indices. We can remove that
in 8.0. Yet, we should remove the settings to make sure they are not used again.

Add NoOps to Lucene for failed delete ops (#33217)
Today we add a NoOp to Lucene and translog if we fail to process an
indexing operation. However, we are only adding NoOps to translog for
delete operations. In order to have a complete history in Lucene, we
should add NoOps of failed delete operations to both Lucene and translog.

Move file-based discovery to core (#33241)
Today we support a static list of seed hosts in core Elasticsearch, and allow a
dynamic list of seed hosts to be provided via a file using the `discovery-file`
plugin. In fact the ability to provide a dynamic list of seed hosts is
increasingly useful, so this change moves this functionality to core
Elasticsearch to avoid the need for a plugin.

Furthermore, in order to start up nodes in integration tests we currently
assign a known port to each node before startup, which unfortunately sometimes
fails if another process grabs the selected port in the meantime. By moving the
`discovery-file` functionality into the core product we can use it to avoid
this race.

This change also moves the expected path to the file from
`$ES_PATH_CONF/discovery-file/unicast_hosts.txt` to
`$ES_PATH_CONF/unicast_hosts.txt`. An example of this file is not included in
distributions.

For BWC purposes the plugin still exists, but does nothing more than create the
example file in the old location, and issue a warning when it is used. We also
continue to support the old location for the file, but warn about its
deprecation.

Given that the parameter is effectively not supported for many months now, that no user has complained about that and that grouping is the expected behaviour, this commit removes support for the parameter.

Send only ops after checkpoint in file-based recovery with soft-deletes (#33190)
Today a file-based recovery will replay all existing translog operations
from the primary on a replica so that that replica can have a full
history in translog as the primary. However, with soft-deletes enabled,
we should not do it because:

1. All operations before the local checkpoint of the safe commit exist in
the commit already.

2. The number of operations before the local checkpoint may be considerable
and requires a significant amount of time to replay on a replica.

Run Third party audit with forbidden APIs CLI (part3/3) (#33052)
The new implementation is functional equivalent with the old, ant based one.
It parses task standard error to get the missing classes and violations in the same way.
I considered re-using ForbiddenApisCliTask but Gradle makes it hard to build inheritance with tasks that have task actions , since the order of the task actions can't be controlled.
This inheritance isn't dully desired either as the third party audit task is much more opinionated and we don't want to expose some of the configuration.
We could probably extract a common base class without any task actions, but probably more trouble than it's worth.

Ensure to generate identical NoOp for the same failure (#33141)
We generate slightly different NoOps in InternalEngine and
TransportShardBulkAction for the same failure.

1. InternalEngine uses Exception#getFailure to generate a message
without the class name: newOp [NoOp{seqNo=1, primaryTerm=1,
reason='Contexts are mandatory in context enabled completion field
[suggest_context]'}].

2. TransportShardBulkAction uses Exception#toString to generate a
message with the class name: NoOp{seqNo=1, primaryTerm=1,
reason='java.lang.IllegalArgumentException: Contexts are mandatory in
context enabled completion field [suggest_context]'}.

If a write operation fails while a replica is recovering, that replica
will possibly receive two different NoOps: one from recovery and one
from replication. These two different NoOps will trip
TranslogWriter#assertNoSeqNumberConflict assertion.

This commit ensures that we generate the same Noop for the same failure.

ShardSearchFailure#readFrom to set index and shardId (#33161)
As part of recent changes made to `ShardOperationFailedException` we introduced `index` and `shardId` members to the base class, but the subclasses are entirely responsible for the serialization of such fields. In the case of `ShardSearchFailure`, we have an additional `SearchShardTarget` instance member which also holds the index and the shardId, hence they get serialized as part of `SearchShardTarget` itself. When de-serializing a `ShardSearchFailure` though, we need to remember to also set the parent class `index` and `shardId` fields otherwise they get lost

Introduce mapping version to index metadata (#33147)
This commit introduces mapping version to index metadata. This value is
monotonically increasing and is updated on mapping updates. This will be
useful in cross-cluster replication so that we can request mapping
updates from the leader only when there is a mapping update as opposed
to the strategy we employ today which is to request a mapping update any
time there is an index metadata update. As index metadata updates can
occur for many reasons other than mapping updates, this leads to some
unnecessary requests and work in cross-cluster replication.

Do not lose default mapper on metadata updates (#33153)
When applying index metadata updates we run through the mappings
updating them if needed. Today if there is not an update to the default
mapper, we can lose the default mapping. This means that, for example,
if we apply a settings update to an index we will lose the default
mapper. This happens because we were not guarding updating the default
mapping with a check that the default mapping was updated in the
metadata update. When there is no update in the metadata update, we need
to continue to preserve the previous default mapping. This commit
achieves this by moving the updating of the default mapping under the
same guard that we use for updating the default mapping source. We add a
test that fails before putting the update under a guard and now passes
after moving the update under the guard.

Fix a mappings update test (#33146)
This commit fixes a mappings update test. The test is broken in the
sense that it passes, but for the wrong reason. The test here is testing
that if we make a mapping update but do not commit that mapping update
then the mapper service still maintains the previous document
mapper. This was not the case long, long ago when a mapping update would
update the in-memory state before the cluster state update was
committed. This test was passing, but it was passing because the mapping
update was never even updated. It was never even updated because it was
encountering a null pointer exception. Of course the in-memory state is
not going to be updated in that case, we are simply going to end up with
a failed cluster state update. Fixing that leads to another issue which
is that the mapping source does not even parse so again we would, of
course, end up with the in-memory state not being modified. We fix these
issues, assert that the result cluster state task completed
successfully, and finally that the in-memory state was not updated since
we never committed the resulting cluster state.

Add proxy support to RemoteClusterConnection (#33062)
This adds support for connecting to a remote cluster through
a tcp proxy. A remote cluster can configured with an additional
`search.remote.$clustername.proxy` setting. This proxy will be used
to connect to remote nodes for every node connection established.
We still try to sniff the remote clsuter and connect to nodes directly
through the proxy which has to support some kind of routing to these nodes.
Yet, this routing mechanism requires the handshake request to include some
kind of information where to route to which is not yet implemented. The effort
to use the hostname and an optional node attribute for routing is tracked
in #32517

Set maxScore for empty TopDocs to Nan rather than 0 (#32938)
We used to set `maxScore` to `0` within `TopDocs` in situations where there is really no score as the size was set to `0` and scores were not even tracked. In such scenarios, `Float.Nan` is more appropriate, which gets converted to `max_score: null` on the REST layer. That's also more consistent with lucene which set `maxScore` to `Float.Nan` when merging empty `TopDocs` (see `TopDocs#merge`).

Refactor Netty4Utils#maybeDie (#33021)
In our Netty layer we have had to take extra precautions against Netty
catching throwables which prevents them from reaching the uncaught
exception handler. This code has taken on additional uses in NIO layer
and now in the scheduler engine because there are other components in
stack traces that could catch throwables and suppress them from reaching
the uncaught exception handler. This commit is a simple cleanup of the
iterative evolution of this code to refactor all uses into a single
method in ExceptionsHelper.

Add settings updater for 2 affix settings (#33050)
Today we can only have non-affix settings updated and consumed _together_.
Yet, there are use-cases where two affix settings depend on each other which
makes using the hard without consuming updates together. Unfortunately, there is
not straight forward way to have N settings updated together in a type-safe way
having 2 still serves a large portion of use-cases.

Allow engine to recover from translog upto a seqno (#33032)
This change allows an engine to recover from its local translog up to
the given seqno. The extended API can be used in these use cases:

When a replica starts following a new primary, it resets its index to
the safe commit, then replays its local translog up to the current
global checkpoint (see #32867).

When a replica starts a peer-recovery, it can initialize the
start_sequence_number to the persisted global checkpoint instead of the
local checkpoint of the safe commit. A replica will then replay its
local translog up to that global checkpoint before accepting remote
translog from the primary. This change will increase the chance of
operation-based recovery. I will make this in a follow-up.

Enable avoiding mmap bootstrap check (#32421)
The maximum map count boostrap check can be a hindrance to users that do
not own the underlying platform on which they are executing
Elasticsearch. This is because addressing it requires tuning the kernel
and a platform provider might now allow this, especially on shared
infrastructure. However, this bootstrap check is not needed if mmapfs is
not in use. Today we do not have a way for the user to communicate that
they are not going to use mmapfs. This commit therefore adds a setting
that enables the user to disallow mmapfs. When mmapfs is disallowed, the
maximum map count bootstrap check is not enforced. Additionally, we
fallback to a different default index store and prevent the explicit use
of mmapfs for an index.

Use a dedicated ConnectionManger for RemoteClusterConnection (#32988)
This change introduces a dedicated ConnectionManager for every RemoteClusterConnection
such that there is not state shared with the TransportService internal ConnectionManager.
All connections to a remote cluster are isolated from the TransportService but still uses
the TransportService and it's internal properties like the Transport, tracing and internal
listener actions on disconnects etc.
This allows a remote cluster connection to have a different lifecycle than a local cluster connection,
also local discovery code doesn't get notified if there is a disconnect on from a remote cluster and
each connection can use it's own dedicated connection profile which allows to have a reduced set of
connections per cluster without conflicting with the local cluster.

Protect scheduler engine against throwing listeners (#32998)
There are two problems with the scheduler engine today. Both relate to
listeners that throw.

The first problem is that any triggered listener that throws a plain old
exception will cause no additional listeners to be triggered for the
event, and will also cause the scheduler to never be invoked again. This
leads to lost events and is bad.

The second problem is that any triggered listener that throws an error
of the fatal kind will not lead to that error because caught by the
uncaught exception handler. This is because the triggered listener is
executed as a future task under a scheduled thread pool executor. A
throwable there goes caught by the JDK framework and set as the outcome
on the future task. Since we never inspect these tasks for their
outcomes, nor is there a good place to do this, we have to handle these
errors ourselves. To do this, we catch them and dispatch them to the
uncaught exception handler via a forked thread. This is similar to our
handling in Netty.

All Translog inner closes should happen after tragedy exception is set (#32674)
All Translog inner closes should happen after tragedy exception is set (#32674)

We faced with the nasty race condition. See #32526
InternalEngine.failOnTragic method has thrown AssertionError.
If you carefully look at if branches in this method, you will spot that its only possible, if either Lucene IndexWriterhas closed from inside or Translog, has closed from inside, but tragedy exception is not set.
For now, let us concentrate on the Translog class.
We found out that there are two methods in Translog - namely rollGeneration and trimOperations that are closing Translog in case of Exception without tragedy exception being set.
This commit fixes these 2 methods. To fix it, we pull tragedyException from TranslogWriter up-to Translog class, because in these 2 methods IndexWriter could be innocent, but still Translog needs to be closed. Also, tragedyException is wrapped with TragicExceptionHolder to reuse CAS/addSuppresed functionality in Translog and TranslogWriter.
Also to protect us in the future and make sure close method is never called from inside Translog special assertion examining stack trace is added. Since we're still targeting Java 8 for runtime - no StackWalker API is used in the implementation.
In the stack-trace checking method, we're considering inner caller not only Translog methods but Translog child classes methods as well. It does mean that Translog is meant for extending it, but it's needed to be able to test this method.

Make Geo Context Mapping Parsing More Strict (#32821)
Currently, if geo context is represented by something other than
geo_point or an object with lat and lon fields, the parsing of it
as a geo context can result in ignoring the context altogether,
returning confusing errors such as number_format_exception or trying
to parse the number specifying as long-encoded hash code. It would also
fail if the geo_point was stored.

This commit makes the mapping parsing more strict and will fail during
mapping update or index creation if the geo context doesn't point to
a geo_point field.

Scripted metric aggregation params._agg/_aggs are replaced by state/states context variables. By default the old params are still present, and a deprecation warning is emitted when Scripted Metric Aggregations are used. A new system property can be used to disable the legacy params. This functionality will be removed in a future revision.

* Fix minor style issue and docs test failure

* Disable deprecated params._agg/_aggs in tests and revise tests to use state/states instead

* Add integration test covering deprecated scripted metrics aggs params._agg/_aggs access

* Disable deprecated params._agg/_aggs in docs integration tests and revise stored scripts to use state/states instead

* Revert unnecessary migrations doc change

A relevant note should be added in the changes destined for 7.0; this PR is going to be backported to 6.x.

* Replace deprecated _agg param bwc integration test with a couple of unit tests

* Fix compatibility test after merge

* Rename backwards compatibility system property per code review feedback

Remove assertion in testDocStats on deletedDocs counter (#32914)
testDocStats test is flaky and sometimes it's failing on jenkins and
failure is not reproducible locally. The reason for this failure is in
timing. If the number of deleted documents is greater than 33% of inserted
documents, Lucene will schedule segments to merge if TieredMergePolicy is
used (it's not the case for LogMergePolicy, but ES is only using
TieredMergePolicy). If this merge is performed before stats are
retrieved - we will get 0 for "deleted" counter.
So basically this counter could be either 0 or numOfDeletedDocs at this point,
but this is the too loose assertion and we decided to remove it at all.

Move CharArrays to core lib (#32851)
This change cleans up some methods in the CharArrays class from x-pack, which
includes the unification of char[] to utf8 and utf8 to char[] conversions that
intentionally do not use strings. There was previously an implementation in
x-pack and in the reloading of secure settings. The method from the reloading
of secure settings was adopted as it handled more scenarios related to the
backing byte and char buffers that were used to perform the conversions. The
cleaned up class is moved into libs/core to allow it to be used by requests
that will be migrated to the high level rest client.

Cat apis: Fix index creation time to use strict date format (#32510)
With the move to java time, the default formatter used by toString on
ZonedDateTime uses optional components for least significant portions of
the date. This commit changes the cat indices api to use a strict date
time format, which will always output milliseconds, even if they are
zero.

Fix test reproducability in AbstractBuilderTestCase setup (#32403)
Currently AbstractBuilderTestCase generates certain random values in its
`beforeTest()` method annotated with @Before only the first time that a test
method in the suite is run while initializing the serviceHolder that we use for
the rest of the test. This changes the values of subsequent random values
and has the effect that when running single methods from a test suite with
"-Dtests.method=*", the random values it sees are different from when the same
test method is run as part of the whole test suite. This makes it hard to use
the reproduction lines logged on failure.

This change runs the inialization of the serviceHolder and the randomization 
connected to it using the test runners master seed, so reproduction by running
just one method is possible again.

Refactor TransportShardBulkAction to better support retries (#31821)
Processing bulk request goes item by item. Sometimes during processing, we need to stop execution and wait for a new mapping update to be processed by the node. This is currently achieved by throwing a `RetryOnPrimaryException`, which is caught higher up. When the exception is caught, we wait for the next cluster state to arrive and process the request again. Sadly this is a problem because all operations that were already done until the mapping change was required are applied again and get new sequence numbers. This in turn means that the previously issued sequence numbers are never replicated to the replicas. That causes the local checkpoint of those shards to be stuck and with it all the seq# based infrastructure.

This commit refactors how we deal with retries with the goal of removing  `RetryOnPrimaryException` and `RetryOnReplicaException` (not done yet). It achieves so by introducing a class `BulkPrimaryExecutionContext` that is used the capture the execution state and allows continuing from where the execution stopped. The class also formalizes the steps each item has to go through:
1) A translation phase for updates
2) Execution phase (always index/delete)
3) Waiting for a mapping update to come in, if needed
4) Requires a retry (for updates and cases where the mapping are still not available after the put mapping call returns)
5) A finalization phase which allows updates to the index/delete result to an update result.

lipsill be54ba39c4 Add expected mapping type to `MapperException` (#31564)
Currently if a document cannot be indexed because it violates the defined 
mapping for the index, a MapperException is thrown. In some cases it is 
useful to expose the expected field type in the exception itself, 
so that the user can react based on the error message. This change adds 
the expected data type to the MapperException.

Core: Fix Java Time DateFormatter printers (#32592)
A bug in the test suite prevented to properly check that all date

This fixes the test and thus also a fair share of formats, that
now use the strict parser for printing.

Switch WritePipelineResponse to AcknowledgedResponse (#32722)
We previously discussed moving the classes extending `AcknowledgedResponse` to
simply use `AcknowledgedResponse`, making the class non-abstract.

This moves the first class to do this, removing `WritePipelineResponse` in the
process.

If we like the way this looks, I will switch the remaining classes over to using
`AcknowledgedResponse`.

Fixes suggestion generics (#32706)
* Fixes suggestion generics

This solves a compile problem in Eclipse where Eclipse could not
resolve the generics for the options field in `PhraseSuggestion.Entry`.
But I think this is also a good change in general because
`PhraseSuggestion.Entry` is now declaring the specific `Option`
implementation it requires rather than `Suggest.Entry.Option` which is
more general and could lead to weird bugs. `CompletionSuggestion.Entry`
and `TermSuggestion.Entry` already declare the more specific class they
use so I think this was an oversight in `PhaseSuggestion.Entry`

Prevent cause from being null in ShardOperationFailedException (#32640)
`ShardOperationFailedException` and corresponding implementors seem to suggest that the cause may be null, case that is also handled in a few places. Yet, it does not seem to be possible in practice for the cause to be null, hence we can clean that up and enforce the cause to be a non null value. This is best done by making `ShardOperationFailedException` an abstract class rather than an interface, which holds the basic member instance that all the subclasses have in common and can also enforce that cause, status and reason are non null.

Preserve index_uuid when creating QueryShardException (#32677)
As part of #32608 we made sure that the fully qualified index name is taken from the query shard context whenever creating a new `QueryShardException`. That change introduced a regression as instead of setting the entire `Index` object to the exception, which holds index name and index uuid, we ended up setting only the index name (including cluster alias). With this commit we make sure that the index uuid does not get lost and we try to lower the chances that a similar bug makes it in another time. That's done by making `QueryShardContext` return the fully qualified `Index` (which also holds the uuid) rather than only the fully qualified index name.

serialize suggestion responses as named writeables (#30284)
Suggestion responses were previously serialized as streamables which
made writing suggesters in plugins with custom suggestion response types
impossible. This commit makes them serialized as named writeables and
provides a facility for registering a reader for suggestion responses
when registering a suggester.

This also makes Suggestion responses abstract, requiring a suggester
implementation to provide its own types. Suggesters which do not need
anything additional to what is defined in Suggest.Suggestion should
provide a minimal subclass.

The existing plugin suggester integration tests are removed and
replaced with an equivalent implementation as an example
plugin.

Expose whether or not the global checkpoint updated (#32659)
It will be useful for future efforts to know if the global checkpoint
was updated. To this end, we need to expose whether or not the global
checkpoint was updated when the state of the replication tracker
updates. For this, we add to the tracker a callback that is invoked
whenever the global checkpoint is updated. For primaries this will be
invoked when the computed global checkpoint is updated based on state
changes to the tracker. For replicas this will be invoked when the local
knowledge of the global checkpoint is advanced from the primary.
