Change signature of Get Repositories Response (#30333)
The Get Repositories response object held a list of RepositoryMetaData
entries. This object does not have the from/toXContent methods that are
needed to expose this to the high level REST client. The
RepositoriesMetaData, however, does, and it also contains a list of
RepositoryMetaData objects within it. So rather than duplicate this
logic or move it (RepositoriesMetaData is a fragment object used by
cluster state), the object holding state in the Response was changed to
use the RepositoriesMetaData instead. This also cleans up the read/write
methods in the response, as they can now use the same read/write in
RepositoriesMetaData, which also were not present in the singular class.

Fix NPE when CumulativeSum agg encounters null/empty bucket (#29641)
Fix NPE when CumulativeSum agg encounters null/empty bucket

If the cusum agg encounters a null value, it's because the value is
missing (like the first value from a derivative agg), the path is
not valid, or the bucket in the path was empty.

Previously cusum would just explode on the null, but this changes it
so we only increment the sum if the value is non-null and finite.
This is safe because even if the cusum encounters all null or empty
buckets, the cumulative sum is still zero (like how the sum agg returns
zero even if all the docs were missing values)

I went ahead and tweaked AggregatorTestCase to allow testing pipelines,
so that I could delete the IT test and reimplement it as AggTests.

Network: Remove http.enabled setting (#29601)
This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.

Fix merging logic of Suggester Options (#29514)
Suggester Options have a collate match field that is returned when the prune 
option is set to true. These values should be merged together in the query 
reduce phase, otherwise good suggestions that result in rare hits in shards with 
results that do not arrive first may be incorrectly marked as not matching the 
collate query.

ReplicationTracker.markAllocationIdAsInSync may hang if allocation is cancelled (#30316)
At the end of recovery, we mark the recovering shard as "in sync" on the primary. From this point on 
the primary will treat any replication failure on it as critical and will reach out to the master to fail the 
shard. To do so, we wait for the local checkpoint of the recovered shard to be above the global 
checkpoint (in order to maintain global checkpoint invariant).

If the master decides to cancel the allocation of the recovering shard while we wait, the method can 
currently hang and fail to return. It will also ignore the interrupts that are triggered by the cancelled 
recovery due to the primary closing. 

Note that this is crucial as this method is called while holding a primary permit. Since the method 
never comes back, the permit is never released. The unreleased permit will then block any primary 
relocation *and* while the primary is trying to relocate all indexing will be blocked for 30m as it 
waits to acquire the missing permit.

Cancelling a peer recovery on the source can leak a primary permit (#30318)
The code in `SourceRecoveryHandler` runs under a `CancellableThreads` instance in order to allow long running operations to be interrupted when the recovery is cancelled. Sadly if this happens at just the wrong moment while acquiring a permit from the primary, that primary can be leaked and never be freed.

Note that this is slightly better than it sounds - we only cancel recoveries on the source side if the primary shard itself is closed.

Allow copying source settings on resize operation (#30255)
Today when an index is created from shrinking or splitting an existing
index, the target index inherits almost none of the source index
settings. This is surprising and a hassle for operators managing such
indices. Given this is the default behavior, we can not simply change
it. Instead, we start by introducing the ability to copy settings. This
flag can be set on the REST API or on the transport layer and it has the
behavior that it copies all settings from the source except non-copyable
settings (a property of a setting introduced in this
change). Additionally, settings on the request will always override.

This change is the first step in our adventure:
 - this flag is added here in 7.0.0 and immediately deprecated
 - this flag will be backported to 6.4.0 and remain deprecated
 - then, we will remove the ability to set this flag to false in 7.0.0
 - finally, in 8.0.0 we will remove this flag and the only behavior will
   be for settings to be copied

Core: Pick inner most parse exception as root cause (#30270)
Just like `ElasticsearchException`, the inner most
`XContentParseException` tends to contain the root cause of the
exception and show be show to the user in the `root_cause` field.

The effectively undoes most of the changes that #29373 made to the
`root_cause` for parsing exceptions. The `type` field still changes from
`parse_exception` to `x_content_parse_exception`, but this seems like a
fairly safe change.

`ElasticsearchWrapperException` *looks* tempting to implement this but
the behavior isn't quite right. `ElasticsearchWrapperExceptions` are
entirely unwrapped until the cause no longer
`implements ElasticsearchWrapperException` but `XContentParseException`
should be unwrapped until its cause is no longer an
`XContentParseException` but no further. In other words,
`ElasticsearchWrapperException` are unwrapped one step too far.

Minor DocWriteResponse changes (#29675)
Remove double if depending on the Result value. It makes little sense to
pass in a boolean flag based on a Result value that we already have,
if that internally is represented again as a `Result` value.

Also changed the `Result` `lowercase` instance member to be computed
based on `name()` instead of `toString()` which is safer and to use
`Locale.ROOT` instead of `Locale.ENGLISH`

Bulk operation fail to replicate operations when a mapping update times out (#30244)
Starting with the refactoring in https://github.com/elastic/elasticsearch/pull/22778 (released in 5.3) we may fail to properly replicate operation when a mapping update on master fails. If a bulk
operations needs a mapping update half way, it will send a request to the master before continuing 
to index the operations. If that request times out or isn't acked (i.e., even one node in the cluster 
didn't process it within 30s), we end up throwing the exception and aborting the entire bulk. This is 
a problem because all operations that were processed so far are not replicated any more to the 
replicas.  Although these operations were never "acked" to the user (we threw an error) it cause the 
local checkpoint on the replicas to lag (on 6.x) and the primary and replica to diverge. 

This PR does a couple of things:
1) Most importantly, treat *any* mapping update failure as a document level failure, meaning only 
    the relevant indexing operation will fail.
2) Removes the mapping update callbacks from `IndexShard.applyIndexOperationOnPrimary` and 
    similar methods for simpler execution. We don't use exceptions any more when a mapping 
    update was successful.

I think we need to do more work here (the fact that a single slow node can prevent those mappings 
updates from being acked and thus fail operations is bad), but I want to keep this as small as I can 
(it is already too big).

_cluster/state should always return cluster_uuid (#30143)
Currently, the only way to get the REST response for the `/_cluster/state`
call to return the `cluster_uuid` is to request the `metadata` metrics,
which is one of the most expensive response structures. However, external
monitoring agents will likely want the `cluster_uuid` to correlate the
response with other API responses whether or not they want cluster
metadata.

Do not ignore request analysis/similarity on resize (#30216)
Today when a resize operation is performed, we copy the analysis,
similarity, and sort settings from the source index. It is possible for
the resize request to include additional index settings including
analysis, similarity, and sort settings. We reject sort settings when
validating the request. However, we silently ignore analysis and
similarity settings on the request that are already set on the source
index. Since it is possible to change the analysis and similarity
settings on an existing index, this should be considered a bug and the
sort of leniency that we abhor. This commit addresses this bug by
allowing the request analysis/similarity settings to override the
existing analysis/similarity settings on the target.

Do not log warn shard not-available exception in replication (#30205)
Since #28049, only fully initialized shards are received write requests.
This enhancement allows us to handle all exceptions. In #28571, we
started strictly handling shard-not-available exceptions and tried to
keep the way we report replication errors to users by only reporting if
the error is not shard-not-available exceptions. However, since then we
unintentionally always log warn for all exception. This change restores
to the previous behavior which logs warn only if an exception is not a
shard-not-available exception.

Build global ordinals terms bucket from matching ordinals (#30166)
The global ordinals terms aggregator has an option to remap global ordinals to
dense ordinal that match the request. This mode is automatically picked when the terms
aggregator is a child of another bucket aggregator or when it needs to defer buckets to an
aggregation that is used in the ordering of the terms.
Though when building the final buckets, this aggregator loops over all possible global ordinals
rather than using the hash map that was built to remap the ordinals.
For fields with high cardinality this is highly inefficient and can lead to slow responses even
when the number of terms that match the query is low.
This change fixes this performance issue by using the hash table of matching ordinals to perform
the pruning of the final buckets for the terms and significant_terms aggregation.
I ran a simple benchmark with 1M documents containing 0 to 10 keywords randomly selected among 1M unique terms.
This field is used to perform a multi-level terms aggregation using rally to collect the response times.
The aggregation below is an example of a two-level terms aggregation that was used to perform the benchmark:

```
"aggregations":{
   "1":{
      "terms":{
         "field":"keyword"
      },
      "aggregations":{
         "2":{
            "terms":{
               "field":"keyword"
            }
         }
      }
   }
}
```

| Levels of aggregation | 50th percentile ms (master) | 50th percentile ms (patch) |
| --- | --- | --- |
| 2 | 640.41ms | 577.499ms |
| 3 | 2239.66ms | 600.154ms |

Fix byte size value equals/hash code test (#29643)
This commit fixes two issues with the byte size value equals/hash code
test.

The first problem is due to a test failure when the original instance is
zero bytes and we pick the mutation branch where we preserve the size
but change the unit. The mutation should result in a different byte size
value but changing the unit on zero bytes still leaves us with zero
bytes.

During the course of fixing this test I discovered another problem. When
we need to randomize size, we could randomly select a size that would
lead to an overflow of Long.MAX_VALUE.

This commit fixes both of these issues.

Nhat Nguyen 42d81a2945 TEST: Unmute testPrimaryRelocationWhileIndexing
Previously we did not put an indexing to a version map if that map does
not require safe access but removed the existing delete tombstone only
if assertion enabled. In #29585, we removed the side-effect caused by
assertion then this test started failing. This failure can be explained
as follows:

- Step 1: Index a doc then delete that doc

- Step 2: The version map can switch to unsafe mode because of
  concurrent refreshes (implicitly called by flushes)

- Step 3: Index a document - the version map won't add this version
  value and won't prune the tombstone (previously it did)

- Step 4: Delete a document - this will return NOT_FOUND instead of
  DELETED because of the stale delete tombstone

This failure is actually fixed by #29619 in which we never leave stale
delete tombstones

Remove bulk fallback for write thread pool (#29609)
The name of the bulk thread pool was renamed to "write" with "bulk" as a
fallback name. This change was made in 6.x for BWC reasons yet in 7.0.0
we are removing this fallback. This commit removes this fallback for the
write thread pool.

Avoid side-effect in VersionMap when assertion enabled (#29585)
Today when a version map does not require safe access, we will skip that
document. However, if the assertion is enabled, we remove the delete
tombstone of that document if existed. This side-effect may accidentally
hide bugs in which stale delete tombstone can be accessed.

This change ensures putAssertionMap not modify the tombstone maps.

Jason Tedor c12c2a6cc9 Rename the bulk thread pool to write thread pool (#29593)
This commit renames the bulk thread pool to the write thread pool. This

execute any document write request (single-document index/delete/update
requests, and bulk requests).

With this change, we add support for fallback settings
thread_pool.bulk.* which will be supported until 7.0.0.

We also add a system property so that the display name of the thread
pool remains as "bulk" if needed to avoid breaking users.

Fix binary doc values fetching in _search (#29567)
Binary doc values are retrieved during the DocValueFetchSubPhase through an instance of ScriptDocValues.
Since 6.0 ScriptDocValues instances are not allowed to reuse the object that they return (https://github.com/elastic/elasticsearch/issues/26775) but BinaryScriptDocValues doesn't follow this restriction and reuses instances of BytesRefBuilder among different documents.
This results in `field` values assigned to the wrong document in the response.
This commit fixes this issue by recreating the BytesRef for each value that needs to be returned.

Zachary Tong cfc9d12acc [TEST] test against scaled value instead of fixed epsilon in MovAvgIT
When comparing doubles, fixed epsilons can fail because the absolute
difference in values may be quite large, even though the relative
difference is tiny (e.g. with two very large numbers).

Instead, we can scale epsilon by the absolute value of the expected
value.  This means we are looking for a diff that is epsilon-percent
away from the value, rather than just epsilon.

This is basically checking the relative error using junit's assertEqual.

Closes #29456, unmutes the test

Remove `flatSettings` support from request classes (#29560)
As part of adding support for new API to the high-level REST client,
we added support for the `flat_settings` parameter to some of our
request classes. We added documentation that such flag is only ever
read by the high-level REST client, but the truth is that it doesn't
do anything given that settings are always parsed back into a `Settings`
object, no matter whether they are returned in a flat format or not.

It was a mistake to add support for this flag in the context of the
high-level REST client, hence this commit removes it.

Enforce translog access via engine (#29542)
Today the translog of an engine is exposed and can be accessed directly.
While this exposure offers much flexibility, it also causes these troubles:

- Inconsistent behavior between translog method and engine method.
For example, rolling a translog generation via an engine also trims
unreferenced files, but translog's method does not.

- An engine does not get notified when critical errors happen in translog
as the access is direct.

This change isolates translog of an engine and enforces all accesses to
translog via the engine.

Introduce analyze thread pool (#29541)
We want to remove the index thread pool as it is no longer needed since
single-document indexing requests are executed as bulk requests
now. Analyze requests are also executed on the index thread pool though
and they need a thread pool to execute on. The bulk thread does not seem
like the right thread pool, let us keep that thread pool conceptually
for bulk requests and free for bulk requests. None of the existing
thread pools make sense for analyze requests either. The generic thread
pool would be a terrible choice since it has an unbounded queue and that
is a bad idea for user-facing APIs. This commit introduces a small by
default (size=1, queue_size=16) thread pool for analyze requests.

Avoid self-deadlock in the translog (#29520)
Today when reading an operation from the current generation fails
tragically we attempt to close the translog. However, by invoking close
before releasing the read lock we end up in self-deadlock because
closing tries to acquire the write lock and the read lock can not be
upgraded to a write lock. To avoid this, we move the close invocation
outside of the try-with-resources that acquired the read lock. As an
extra guard against this, we document the problem and add an assertion
that we are not trying to invoke close while holding the read lock.

Add useful message when no input from terminal (#29369)
Today when a user runs a CLI tool with standard input closed and no tty
attached, the result from reading is null and this usually leads to a
null pointer exception when we try to parse this input. This arises for
example when the user runs the plugin installer through a Docker
container without leaving standard input open and attaching a tty
(docker exec <container ID> bin/elasticsearch-plugin install). When we
try to read that the user accepts the plugin requiring additional
security permissions we will get back null. This commit addresses this
for all cases by throwing an illegal state exception. The solution for
the user is leave standard input open and attach a tty (or, for some
tools, use batch mode).

Close translog writer if exception on write channel (#29401)
Today we close the translog write tragically if we experience any I/O
exception on a write. These tragic closes lead to use closing the
translog and failing the engine. Yet, there is one case that is missed
which is when we touch the write channel during a read (checking if
reading from the writer would put us past what has been flushed). This
commit addresses this by closing the writer tragically if we encounter
an I/O exception on the write channel while reading. This becomes
interesting when we consider that this method is invoked from the engine
through the translog as part of getting a document from the
translog. This means we have to consider closing the translog here as
well which will cascade up into us finally failing the engine.

Note that there is no semantic change to, for example, primary/replica
resync and recovery. These actions will take a snapshot of the translog
which syncs the translog to disk. If an I/O exception occurs during the
sync we already close the writer tragically and once we have synced we
do not ever read past the position that was synced while taking the
snapshot.

Improve NodeVersionAllocationDecider messages (#29356)
Since #26542 the NodeVersionAllocationDecider tries to explain its NO decisions
as follows:

    ... may not support codecs or postings formats for a newer Lucene version

However, this message often appears during a rolling upgrade, and experience
has shown that it seems to cause more confusion and worry than it needs to.
This change fixes that by removing the explanation again, reducing the message
to a statement of fact about the respective nodes' versions.

Additionally, the same wording was used for version incompatibilities when
allocating a primary (vs its previous location) and a replica (vs its primary).
This change separates these two cases so they can have separate, clearer
wording.

Enhance error for out of bounds byte size settings (#29338)
Today when you input a byte size setting that is out of bounds for the
setting, you get an error message that indicates the maximum value of
the setting. The problem is that because we use ByteSize#toString, we
end up with a representation of the value that does not really tell you
what the bound is. For example, if the bound is 2^31 - 1 bytes, the
output would be 1.9gb which does not really tell you want the limit as
there are many byte size values that we format to the same 1.9gb with
ByteSize#toString. We have a method ByteSize#getStringRep that uses the
input units to the value as the output units for the string
representation, so we end up with no loss if we use this to report the
bound. This commit does this.

Align cat thread pool info to thread pool config (#29195)
Today we report thread pool info using a common object. This means that
we use a shared set of terminology that is not consistent with the
terminology used to the configure thread pools. This holds in particular
for the minimum and maximum number of threads in the thread pool where
we use the following terminology:
 thread pool info | fixed | scaling
  min                core    size
  max                max     size

A previous change addressed this for the nodes info API. This commit
changes the display of thread pool info in the cat thread pool API too
to be dependent on the type of the thread pool so that we can align the
terminology in the output of thread pool info with the terminology used
to configure a thread pool.

Don't break allocation if resize source index is missing (#29311)
DiskThresholdDecider currently assumes that the source index of a resize operation (e.g. shrink)
is available, and throws an IndexNotFoundException otherwise, thereby breaking any kind of shard
allocation. This can be quite harmful if the source index is deleted during a shrink, or if the source
index is unavailable during state recovery.

While this behavior has been partly fixed in 6.1 and above (due to #26931), it relies on the order in
which AllocationDeciders are executed (i.e. that ResizeAllocationDecider returns NO, ensuring that
DiskThresholdDecider does not run, something that for example does not hold for the allocation
explain API).

This change adds a more complete fix, and also solves the situation for 5.6.

Begin moving XContent to a separate lib/artifact (#29300)
* Begin moving XContent to a separate lib/artifact

This commit moves a large portion of the XContent code from the `server` project
to the `libs/xcontent` project. For the pieces that have been moved, some
helpers have been duplicated to allow them to be decoupled from ES helper
classes. In addition, `Booleans` and `CheckedFunction` have been moved to the
`elasticsearch-core`  project.

This decoupling is a move so that we can eventually make things like the
high-level REST client not rely on the entire ES jar, only the parts it needs.

There are some pieces that are still not decoupled, in particular some of the
XContent tests still remain in the server project, this is because they test a
large portion of the pluggable xcontent pieces through
`XContentElasticsearchException`. They may be decoupled in future work.
Additionally, there may be more piecese that we want to move to the xcontent lib
in the future that are not part of this PR, this is a starting point.

Fix handling of bad requests (#29249)
Today we have a few problems with how we handle bad requests:
 - handling requests with bad encoding
 - handling requests with invalid value for filter_path/pretty/human
 - handling requests with a garbage Content-Type header

There are two problems:
 - in every case, we give an empty response to the client
 - in most cases, we leak the byte buffer backing the request!

These problems are caused by a broader problem: poor handling preparing
the request for handling, or the channel to write to when the response
is ready. This commit addresses these issues by taking a unified
approach to all of them that ensures that:
 - we respond to the client with the exception that blew us up
 - we do not leak the byte buffer backing the request

Allow _update and upsert to read from the transaction log (#29264)
We historically removed reading from the transaction log to get consistent
results from _GET calls. There was also the motivation that the read-modify-update
principle we apply should not be hidden from the user. We still agree on the fact
that we should not hide these aspects but the impact on updates is quite significant
especially if the same documents is updated before it's written to disk and made serachable.

This change adds back the ability to read from the transaction log but only for update calls.
Calls to the _GET API will always do a refresh if necessary to return consistent results ie.
if stored fields or DocValues Fields are requested.

The former closes the scheduler while the latter doesn't, leaving threads lingering.

Do not optimize append-only if seen normal op with higher seqno (#28787)
When processing an append-only operation, primary knows that operations 
can only conflict with another instance of the same operation. This is
true as the id was freshly generated. However this property doesn't hold
for replicas. As soon as an auto-generated ID was indexed into the
primary, it can be exposed to a search and users can issue a follow up
operation on it. In extremely rare cases, the follow up operation can be
arrived and processed on a replica before the original append-only
request. In this case we can't simply proceed with the append-only
request and blindly add it to the index without consulting the version
map. 

The following scenario can cause difference between primary and
replica.

1. Primary indexes an auto-gen-id doc. (id=X, v=1, s#=20)
2. A refresh cycle happens on primary
3. The new doc is picked up and modified - say by a delete by query
   request - Primary gets a delete doc (id=X, v=2, s#=30)
4. Delete doc is processed first on the replica (id=X, v=2, s#=30)
5. Indexing operation arrives on the replica, since it's an auto-gen-id
   request and the retry marker is lower, we put it into lucene without 
   any check. Replica has a doc the primary doesn't have.

To deal with a potential conflict between an append-only operation and a 
normal operation on replicas, we need to rely on sequence numbers. This
commit maintains the max seqno of non-append-only operations on replica
then only apply optimization for an append-only operation only if its
seq# is higher than the seq# of all non-append-only.

Prune only gc deletes below local checkpoint (#28790)
Once a document is deleted and Lucene is refreshed, we will not be able 
to look up the `version/seq#` associated with that delete in Lucene. As
conflicting operations can still be indexed, we need another mechanism
to remember these deletes. Therefore deletes should still be stored in
the Version Map, even after Lucene is refreshed. Obviously, we can't
remember all deletes forever so a trimming mechanism is needed.
Currently, we remember deletes for at least 1 minute (the default GC
deletes cycle) and clean them periodically. This is, at the moment, the
best we can do on the primary for user facing APIs but this arbitrary
time limit is problematic for replicas. Furthermore, we can't rely on
the primary and replicas doing the trimming in a synchronized manner,
and failing to do so results in the replica and primary making different
decisions. 

The following scenario can cause inconsistency between
primary and replica.

1. Primary index doc (index, id=1, v2)
2. Network packet issue causes index operation to back off and wait
3. Primary deletes doc (delete, id=1, v3)
4. Replica processes delete (delete, id=1, v3)
5. 1+ minute passes (GC deletes runs replica)
6. Indexing op is finally sent to the replica which no processes it 
   because it forgot about the delete.

We can reply on sequence-numbers to prevent this issue. If we prune only 
deletes whose seqno at most the local checkpoint, a replica will
correctly remember what it needs. The correctness is explained as
follows:

Suppose o1 and o2 are two operations on the same document with seq#(o1) 
< seq#(o2), and o2 arrives before o1 on the replica. o2 is processed
normally since it arrives first; when o1 arrives it should be discarded:
 
1. If seq#(o1) <= LCP, then it will be not be added to Lucene, as it was
  already previously added.

2. If seq#(o1)  > LCP, then it depends on the nature of o2:
  - If o2 is a delete then its seq# is recorded in the VersionMap,
    since seq#(o2) > seq#(o1) > LCP, so a lookup can find it and
    determine that o1 is stale.
  
  - If o2 is an indexing then its seq# is either in Lucene (if
    refreshed) or the VersionMap (if not refreshed yet), so a 
    real-time lookup can find it and determine that o1 is stale.

In this PR, we prefer to deploy a single trimming strategy, which 
satisfies both requirements, on primary and replicas because:

- It's simpler - no need to distinguish if an engine is running at
primary mode or replica mode or being promoted.

- If a replica subsequently is promoted, user experience is fully
maintained as that replica remembers deletes for the last GC cycle.

However, the version map may consume less memory if we deploy two 
different trimming strategies for primary and replicas.

Boaz Leskes bca264699a remove testUnassignedShardAndEmptyNodesInRoutingTable
testUnassignedShardAndEmptyNodesInRoutingTable and that test is as old as time and does a very bogus thing.
it is an IT test which extracts the GatewayAllocator from the node and tells it to allocated unassigned
shards, while giving it a conjured cluster state with no nodes in it (it uses the DiscoveryNodes.EMPTY_NODES.
This is never a cluster state we want to reroute on (we always have at least master node in it).
I'm going to just delete the test as I don't think it adds much value.

Fold EngineDiskUtils into Store, for better lock semantics (#29156)
#28245 has introduced the utility class`EngineDiskUtils` with a set of methods to prepare/change
translog and lucene commit points. That util class bundled everything that's needed to create and
empty shard, bootstrap a shard from a lucene index that was just restored etc. 

In order to safely do these manipulations, the util methods acquired the IndexWriter's lock. That
would sometime fail due to concurrent shard store fetching or other short activities that require the
files not to be changed while they read from them. 

Since there is no way to wait on the index writer lock, the `Store` class has other locks to make
sure that once we try to acquire the IW lock, it will succeed. To side step this waiting problem, this
PR folds `EngineDiskUtils` into `Store`. Sadly this comes with a price - the store class doesn't and
shouldn't know about the translog. As such the logic is slightly less tight and callers have to do the
translog manipulations on their own.

Optimize the composite aggregation for match_all and range queries (#28745)
This change refactors the composite aggregation to add an execution mode that visits documents in the order of the values
present in the leading source of the composite definition. This mode does not need to visit all documents since it can early terminate
the collection when the leading source value is greater than the lowest value in the queue.
Instead of collecting the documents in the order of their doc_id, this mode uses the inverted lists (or the bkd tree for numerics) to collect documents
in the order of the values present in the leading source.
For instance the following aggregation:

```
"composite" : {
  "sources" : [
    { "value1": { "terms" : { "field": "timestamp", "order": "asc" } } }
  ],
  "size": 10
}
```
... can use the field `timestamp` to collect the documents with the 10 lowest values for the field instead of visiting all documents.
For composite aggregation with more than one source the execution can early terminate as soon as one of the 10 lowest values produces enough
composite buckets. For instance if visiting the first two lowest timestamp created 10 composite buckets we can early terminate the collection since it
is guaranteed that the third lowest timestamp cannot create a composite key that compares lower than the one already visited.

This mode can execute iff:
 * The leading source in the composite definition uses an indexed field of type `date` (works also with `date_histogram` source), `integer`, `long` or `keyword`.
 * The query is a match_all query or a range query over the field that is used as the leading source in the composite definition.
 * The sort order of the leading source is the natural order (ascending since postings and numerics are sorted in ascending order only).

If these conditions are not met this aggregation visits each document like any other agg.

Yu 4a8099c696 Change BroadcastResponse from ToXContentFragment to ToXContentObject (#28878)
While working on #27799, we find that it might make sense to change BroadcastResponse from ToXContentFragment to ToXContentObject, seeing that it's rather a complete XContent object and also the other Responses are normally ToXContentObject.

By doing this, we can also move the XContent build logic of BroadcastResponse's subclasses, from Rest Layer to the concrete classes themselves.

Harden periodically check to avoid endless flush loop (#29125)
In #28350, we fixed an endless flushing loop which may happen on 
replicas by tightening the relation between the flush action and the
periodically flush condition.

1. The periodically flush condition is enabled only if it is disabled 
after a flush.

2. If the periodically flush condition is enabled then a flush will
actually happen regardless of Lucene state.

(1) and (2) guarantee that a flushing loop will be terminated. Sadly, 
the condition 1 can be violated in edge cases as we used two different
algorithms to evaluate the current and future uncommitted translog size.

- We use method `uncommittedSizeInBytes` to calculate current 
  uncommitted size. It is the sum of translogs whose generation at least
the minGen (determined by a given seqno). We pick a continuous range of
translogs since the minGen to evaluate the current uncommitted size.

- We use method `sizeOfGensAboveSeqNoInBytes` to calculate the future 
  uncommitted size. It is the sum of translogs whose maxSeqNo at least
the given seqNo. Here we don't pick a range but select translog one by
one.

Suppose we have 3 translogs `gen1={#1,#2}, gen2={}, gen3={#3} and 
seqno=#1`, `uncommittedSizeInBytes` is the sum of gen1, gen2, and gen3
while `sizeOfGensAboveSeqNoInBytes` is the sum of gen1 and gen3. Gen2 is
excluded because its maxSeqno is still -1.

This commit removes both `sizeOfGensAboveSeqNoInBytes` and 
`uncommittedSizeInBytes` methods, then enforces an engine to use only
`sizeInBytesByMinGen` method to evaluate the periodically flush condition.

Decouple more classes from XContentBuilder and make builder strict (#29197)
This commit decouples `BytesRef`, `Releaseable`, and `TimeValue` from
XContentBuilder, and paves the way for doupling `ByteSizeValue` as well. It
moves much of the Lucene and Joda encoding into a new SPI extension that is
loaded by XContentBuilder to know how to encode these values.

Part of doing this also allows us to make JSON encoding strict, as we no longer
allow just any old object to be passed (in the past it was possible to get json
that was `"field": "java.lang.Object@d8355a8"` if no one was careful about what
was passed in).

Add new setting to disable persistent tasks allocations (#29137)
This commit adds a new setting `cluster.persistent_tasks.allocation.enable`
that can be used to enable or disable the allocation of persistent tasks.
The setting accepts the values `all` (default) or `none`. When set to
none, the persistent tasks that are created (or that must be reassigned)
won't be assigned to a node but will reside in the cluster state with
a no "executor node" and a reason describing why it is not assigned:

```
"assignment" : {
  "executor_node" : null,
  "explanation" : "persistent task [foo/bar] cannot be assigned [no
  persistent task assignments are allowed due to cluster settings]"
}

The assumption here is that we will no longer be making a release from

actually released, we do not want to leave behind any versions that
would require a snapshot build. We do have a test that verifies that all
released versions are present here, so if another release is performed
from the 6.1 branch, that test will fail and we will know to add the
version constant at that time.

This removes the usage of `BytesArray` and `BytesReference` from

Add pluggable XContentBuilder writers and human readable writers (#29120)
* Add pluggable XContentBuilder writers and human readable writers

This adds the ability to use SPI to plug in writers for XContentBuilder. By
implementing the XContentBuilderProvider class we can allow Elasticsearch to
plug in different ways to encode types to JSON.

Important caveat for this, we should always try to have the class implement
`ToXContentFragment` first, however, in the case of classes from our
dependencies (think Joda classes or Lucene classes) we need a way to specify
writers for these classes.

This also makes the human-readable field writers generic and pluggable, so that
we no longer need to tie XContentBuilder to things like `TimeValue` and
`ByteSizeValue`. Contained as part of this moves all the TimeValue human
readable fields to the new `humanReadableField` method. A future commit will
move the `ByteSizeValue` calls over to this method.
