Introduce retention leases versioning (#37951)
Because concurrent sync requests from a primary to its replicas could be
in flight, it can be the case that an older retention leases collection
arrives and is processed on the replica after a newer retention leases
collection has arrived and been processed. Without a defense, in this
case the replica would overwrite the newer retention leases with the
older retention leases. This commit addresses this issue by introducing
a versioning scheme to retention leases. This versioning scheme is used
to resolve out-of-order processing on the replica. We persist this
version into Lucene and restore it on recovery. The encoding of
retention leases is starting to get a little ugly. We can consider
addressing this in a follow-up.

Default include_type_name to false in the yml test harness. (#38058)
This PR removes the temporary change we made to the yml test harness in #37285
to automatically set `include_type_name` to `true` in index creation requests
if it's not already specified. This is possible now that the vast majority of
index creation requests were updated to be typeless in #37611. A few additional
tests also needed updating here.

Additionally, this PR updates the test harness to set `include_type_name` to
`false` in index creation requests when communicating with 6.x nodes. This
mirrors the logic added in #37611 to allow for typeless document write requests
in test set-up code. With this update in place, we can remove many references
to `include_type_name: false` from the yml tests.

Universal cluster bootstrap method for tests with autoMinMasterNodes=false (#38038)
Currently, there are a few tests that use autoMinMasterNodes=false and
hence override addExtraClusterBootstrapSettings, mostly this is 10-30
lines of codes that are copy-pasted from class to class.

This PR introduces `InternalTestCluster.setBootstrapMasterNodeIndex`
which is suitable for all classes and copy-paste could be removed.

Removing code is always a good thing!

Fix Two Races that Lead to Stuck Snapshots (#37686)
* Fixes two broken spots:
    1. Master failover while deleting a snapshot that has no shards will get stuck if the new master finds the 0-shard snapshot in `INIT` when deleting
    2. Aborted shards that were never seen in `INIT` state by the `SnapshotsShardService` will not be notified as failed, leading to the snapshot staying in `ABORTED` state and never getting deleted with one or more shards stuck in `ABORTED` state
* Tried to make fixes as short as possible so we can backport to `6.x` with the least amount of risk
* Significantly extended test infrastructure to reproduce the above two issues
  * Two new test runs:
      1. Reproducing the effects of node disconnects/restarts in isolation
      2. Reproducing the effects of disconnects/restarts in parallel with shard relocations and deletes
* Relates #32265 
* Closes #32348

geotile_grid implementation (#37842)
Implements `geotile_grid` aggregation

This patch refactors previous implementation https://github.com/elastic/elasticsearch/pull/30240

This code uses the same base classes as `geohash_grid` agg, but uses a different hashing
algorithm to allow zoom consistency.  Each grid bucket is aligned to Web Mercator tiles.

Handle scheduler exceptions (#38014)
Scheduler.schedule(...) would previously assume that caller handles
exception by calling get() on the returned ScheduledFuture.
schedule() now returns a ScheduledCancellable that no longer gives
access to the exception. Instead, any exception thrown out of a
scheduled Runnable is logged as a warning.

This is a continuation of #28667, #36137 and also fixes #37708.

Push primary term to replication tracker (#38044)
This commit pushes the primary term into the replication tracker. This
is a precursor to using the primary term to resolving ordering problems
for retention leases. Namely, it can be that out-of-order retention
lease sync requests arrive on a replica. To resolve this, we need a
tuple of (primary term, version). For this to be, the primary term needs
to be accessible in the replication tracker. As the primary term is part
of the replication group anyway, this change conceptually makes sense.

Introduce ability to minimize round-trips in CCS (#37828)
With #37566 we have introduced the ability to merge multiple search responses into one. That makes it possible to expose a new way of executing cross-cluster search requests, that makes CCS much faster whenever there is network latency between the CCS coordinating node and the remote clusters. The coordinating node can now send a single search request to each remote cluster, which gets reduced by each one of them. from + size results are requested to each cluster, and the reduce phase in each cluster is non final (meaning that buckets are not pruned and pipeline aggs are not executed). The CCS coordinating node performs an additional, final reduction, which produces one search response out of the multiple responses received from the different clusters.

This new execution path will be activated by default for any CCS request unless a scroll is provided or inner hits are requested as part of field collapsing. The search API accepts now a new parameter called ccs_minimize_roundtrips that allows to opt-out of the default behaviour.

Removes typed calls from YAML REST tests (#37611)
This PR attempts to remove all typed calls from our YAML REST tests. The PR adds include_type_name: false to create index requests that use a mapping and also to put mapping requests. It also removes _type from index requests where they haven't already been removed. The PR ignores tests named *_with_types.yml since this are specifically testing typed API behaviour.

The change also includes changing the test harness to add the type _doc to index, update, get and bulk requests that do not specify the document type when the test is running against a mixed 7.x/6.x cluster.

Elasticsearch support to JSON logging (#36833)
In order to support JSON log format, a custom pattern layout was used and its configuration is enclosed in ESJsonLayout. Users are free to use their own patterns, but if smooth Beats integration is needed, they should use ESJsonLayout. EvilLoggerTests are left intact to make sure user's custom log patterns work fine.

To populate additional fields node.id and cluster.uuid which are not available at start time, 
a cluster state update will have to be received and the values passed to log4j pattern converter.
A ClusterStateObserver.Listener is used to receive only one ClusteStateUpdate. Once update is received the nodeId and clusterUUid are set in a static field in a NodeAndClusterIdConverter. 

Following fields are expected in JSON log lines: type, tiemstamp, level, component, cluster.name, node.name, node.id, cluster.uuid, message, stacktrace
see ESJsonLayout.java for more details and field descriptions

Docker log4j2 configuration is now almost the same as the one use for ES binary. 
The only difference is that docker is using console appenders, whereas ES is using file appenders.

Track total hits up to 10,000 by default (#37466)
This commit changes the default for the `track_total_hits` option of the search request
to `10,000`. This means that by default search requests will accurately track the total hit count
up to `10,000` documents, requests that match more than this value will set the `"total.relation"`
to `"gte"` (e.g. greater than or equals) and the `"total.value"` to `10,000` in the search response.
Scroll queries are not impacted, they will continue to count the total hits accurately.
The default is set back to `true` (accurate hit count) if `rest_total_hits_as_int` is set in the search request.
I choose `10,000` as the default because that's also the number we use to limit pagination. This means that users will be able to know how far they can jump (up to 10,000) even if the total number of hits is not accurate.

Extract message serialization from `TcpTransport` (#37034)
This commit introduces a NetworkMessage class. This class has two
subclasses - InboundMessage and OutboundMessage. These messages can
be serialized and deserialized independent of the transport. This allows
more granular testing. Additionally, the serialization mechanism is now
a simple Supplier. This builds the framework to eventually move the
serialization of transport messages to the network thread. This is the
one serialization component that is not currently performed on the
network thread (transport deserialization and http serialization and
deserialization are all on the network thread).

modifies the nio-transport to have 0 http workers be default. If the

on the transport worker threads. The http worker setting will still exist
in case the user would like to configure dedicated workers. Additionally,
this commmit deletes dedicated acceptor threads. We have never had these
for the netty transport and they can be added back if a need is
determined in the future.

Remove initial_master_nodes on node restart (#37580)
Some tests (e.g. testRestoreIndexWithShardsMissingInLocalGateway) were split-braining since
being switched to Zen2 because the bootstrap setting was left around when nodes got restarted
with data folders wiped.

The test in question here was starting one node (which autobootstrapped to that single node), then
another node. The first node was then shut down (after excluding it from the voting configuration),
its data folder wiped, and restarted. After restart, the node had an empty data folder yet
initial_master_nodes set to itself (i.e. same name). This made the node sometimes form a cluster of
its own, and not rejoin the existing cluster with the other node.

We make sure to specify include_type_name=true during xContent parsing,
so we continue to test the legacy typed responses. XContent generation
for the typeless responses is currently only covered by REST tests,
but we will be adding unit test coverage for these as we implement
each typeless API in the Java HLRC.

This commit also refactors GetMappingsResponse to follow the same appraoch
as the other mappings-related responses, where we read include_type_name
out of the xContent params, instead of creating a second toXContent method.
This gives better consistency in the response parsing code.

* Fix more REST tests.

* Improve some wording in the create index documentation.

* Add a note about types removal in the create index docs.

* Fix SmokeTestMonitoringWithSecurityIT#testHTTPExporterWithSSL.

* Make sure to mention include_type_name in the REST docs for affected APIs.

Reduce recovery time with compress or secure transport (#36981)
Today file-chunks are sent sequentially one by one in peer-recovery. This is a
correct choice since the implementation is straightforward and recovery is
network bound in most of the time. However, if the connection is encrypted, we
might not be able to saturate the network pipe because encrypting/decrypting
are cpu bound rather than network-bound.

With this commit, a source node can send multiple (default to 2) file-chunks
without waiting for the acknowledgments from the target.

* Made the ability to wipe stopped datanode's data public on the internal test cluster and used it to ensure correct behaviour on the fixed test
   * Previously it simply passed because the test finished before the index went green and would NPE when the index was green at the time of the shard store status request, that would then come up empty

[Close Index API] Add unique UUID to ClusterBlock (#36775)
This commit adds a unique id to cluster blocks, so that they can be uniquely 
identified if needed. This is important for the Close Index API where multiple 
concurrent closing requests can be executed at the same time. By adding a 
UUID to the cluster block, we can generate unique "closing block" that can 
later be verified on shards and then checked again from the cluster state 
before closing the index. When the verification on shard is done, the closing 
block is replaced by the regular INDEX_CLOSED_BLOCK instance.

If something goes wrong, calling the Open Index API will remove the block.

Introduce shard history retention leases (#37167)
This commit is the first in a series which will culminate with
fully-functional shard history retention leases.

Shard history retention leases are aimed at preventing shard history
consumers from having to fallback to expensive file copy operations if
shard history is not available from a certain point. These consumers
include following indices in cross-cluster replication, and local shard
recoveries. A future consumer will be the changes API.

Further, index lifecycle management requires coordinating with some of
these consumers otherwise it could remove the source before all
consumers have finished reading all operations. The notion of shard
history retention leases that we are introducing here will also be used
to address this problem.

Shard history retention leases are a property of the replication group
managed under the authority of the primary. A shard history retention
lease is a combination of an identifier, a retaining sequence number, a
timestamp indicating when the lease was acquired or renewed, and a
string indicating the source of the lease. Being leases they have a
limited lifespan that will expire if not renewed. The idea of these
leases is that all operations above the minimum of all retaining
sequence numbers will be retained during merges (which would otherwise
clear away operations that are soft deleted). These leases will be
periodically persisted to Lucene and restored during recovery, and
broadcast to replicas under certain circumstances.

This commit is merely putting the basics in place. This first commit
only introduces the concept and integrates their use with the soft
delete retention policy. We add some tests to demonstrate the basic
management is correct, and that the soft delete policy is correctly
influenced by the existence of any retention leases. We make no effort
in this commit to implement any of the following:
 - timestamps
 - expiration
 - persistence to and recovery from Lucene
 - handoff during primary relocation
 - sharing retention leases with replicas
 - exposing leases in shard-level statistics
 - integration with cross-cluster replication

These will occur individually in follow-up commits.

Add the ability to set the number of hits to track accurately (#36357)
In Lucene 8 searches can skip non-competitive hits if the total hit count is not requested.
It is also possible to track the number of hits up to a certain threshold. This is a trade off to speed up searches while still being able to know a lower bound of the total hit count. This change adds the ability to set this threshold directly in the track_total_hits search option. A boolean value (true, false) indicates whether the total hit count should be tracked in the response. When set as an integer this option allows to compute a lower bound of the total hits while preserving the ability to skip non-competitive hits when enough matches have been collected.

Add support for local cluster alias to SearchRequest (#36997)
With the upcoming cross-cluster search alternate execution mode, the CCS
 node will be able to split a CCS request into multiple search requests,
 one per remote cluster involved. In order to do that, the CCS node has
to be able to signal to each remote cluster that such sub-requests are
part of a CCS request. Each cluster does not know about the other
clusters involved, and does not know either what alias it is given in
the CCS node, hence the CCS coordinating node needs to be able to provide
the alias as part of the search request so that it is used as index prefix
in the returned search hits.

The cluster alias is a notion that's already supported in the search shards
iterator and search shard target, but it is currently used in CCS as both
 index prefix and connection lookup key when fanning out to all the shards.
With CCS alternate execution mode the provided cluster alias needs to be
used only as index prefix, as shards are local to each cluster hence no
cluster alias should be used for connection lookups.

The local cluster alias can be set to the SearchRequest at the transport layer
only, and its constructor/getter methods are package private.

Only compress responses if request was compressed (#36867)
This is a follow-up to some discussions around #36399. Currently we have
relatively confusing compression behavior where compression can be
configured for requests based on transport.compress or a specific
setting for a remote cluster. However, we can only compress responses
based on transport.compress as we do not know where a request is
coming from (currently).

This commit modifies the behavior to NEVER compress responses based on
settings. Instead, a response will only be compressed if the request was
compressed. This commit also updates the documentation to more clearly
described transport level compression.

[Zen2] Change unsafe bootstrap nodes count to nodes list in tests (#36559)
This commit modifies ESSingleNodeTestCase and ESIntegTestCase and
several concrete test classes to use node names when bootstrapping the
cluster.

Today ClusterBootstrapService.INITIAL_MASTER_NODE_COUNT_SETTING
setting is used to bootstrap clusters in tests. Instead, we want to use
ClusterBootrstapService.INITIAL_MASTER_NODES_SETTING and get rid of
the former setting eventually.

There were two main problems when refactoring InternalTestCluster:

1. Nodes are created one-by-one in buildNode method. And node.name
is created in this method as well. It's not suitable for bootstrapping,
because we need to have the names of all master eligible nodes in
advance, before creating the node with bootstrapping configuration set.
We address this issue by separating buildNode into two methods:
getNodeSettings and buildNode. We first iterate over all nodes to
get nodes settings, then change the setting for the bootstrapping node
and then proceed with building the node.
2. If autoManageMinMasterNodes = false, there is no way for the test to
set the list of bootstrapping nodes because node names are not known in
advance. This problem is solved by adding updateNodesSettings method
to NodeConfigurationSource and ESIntegTestCase (which could be
overridden by concrete integration test class). Once we have the list
of settings for all nodes, the integration test class is allowed to
update it. In our case, we update the
ClusterBootrstapService.INITIAL_MASTER_NODES_SETTING setting.

Add raw sort values to SearchSortValues transport serialization (#36617)
In order for CCS alternate execution mode (see #32125) to be able to do the final reduction step on the CCS coordinating node, we need to serialize additional info in the transport layer as part of each `SearchHit`. Sort values are already present but they are formatted according to the provided `DocValueFormat` provided. The CCS node needs to be able to reconstruct the lucene `FieldDoc` to include in the `TopFieldDocs` and `CollapseTopFieldDocs` which will feed the `mergeTopDocs` method used to reduce multiple search responses (one per cluster) into one.

This commit adds such information to the `SearchSortValues` and exposes it through a new getter method added to `SearchHit` for retrieval. This info is only serialized at transport and never printed out at REST.

Unify transport settings naming (#36623)
This commit updates our transport settings for 7.0. It generally takes a
few approaches. First, for normal transport settings, it usestransport.
instead of transport.tcp. Second, it uses transport.tcp, http.tcp,
or network.tcp for all settings that are proxies for OS level socket
settings. Third, it marks the network.tcp.connect_timeout setting for
removal. Network service level settings are only settings that apply to
both the http and transport modules. There is no connect timeout in
http. Fourth, it moves all the transport settings to a single class
TransportSettings similar to the HttpTransportSettings class.

This commit does not actually remove any settings. It just adds the new
renamed settings and adds todos for settings that will be deprecated.

Increase coverage in SearchSortValuesTests (#36597)
SearchSortValuesTests extends now `AbstractSerializingTestCase` which removes some code duplication and standardizes the way we test `fromXContent`, serialization and equals/hashcode.

Also, we were never creating `SearchSortValues` through their public constructor that accept an array of `DocValueFormat` together with the array of raw sort values. That is covered now, which involved some conversion from `BytesRef` to String in the test.

Also, the previous test was not using doing any equality check against the original and parsed versions in `testFromXContent` due to values being parsed with different types in some cases, which is now covered by converting those values using a new method added to `RandomObjects`. The code was already there as part of `randomStoredFieldValues`, but it is now exposed to be used in other scenarios.

Add sort and collapse info to SearchHits transport serialization (#36555)
In order for CCS alternate execution mode (see #32125) to be able to do the final reduction step on the CCS coordinating node, we need to serialize additional info in the transport layer as part of the `SearchHits`, specifically:

- lucene `SortField[]` which contains info about the fields that sorting was performed on and their type, which depends on mappings (that the CCS node does not know about)
- collapse field (`String`) that field collapsing was executed on, if requested
- collapse values (`Object[]`) that field collapsing was based on, if requested

This info is needed to be able to reconstruct the `TopFieldDocs` or `CollapseFieldTopDocs` in the CCS coordinating node to feed the `mergeTopDocs` method and reduce multiple search responses received (one per cluster) into one.

This commit adds such information to the `SearchHits` class. It's nullable info that is not serialized through the REST layer. `SearchPhaseController` sets such info at the end of the hits reduction phase.

[Close Index API] Refactor MetaDataIndexStateService (#36354)
The commit changes how indices are closed in the MetaDataIndexStateService. 
It now uses a 3 steps process where writes are blocked on indices to be closed, 
then some verifications are done on shards using the TransportVerifyShardBeforeCloseAction 
added in #36249, and finally indices states are moved to CLOSE and their routing 
tables removed.

The closing process also takes care of using the pre-7.0 way to close indices if the 
cluster contains mixed version of nodes and a node does not support the TransportVerifyShardBeforeCloseAction. It also closes unassigned indices.

[refactor] add Environment in BootstrapContext (#36573)
There are certain BootstrapCheck checks that may need access environment-specific
values. Watcher's EncryptSensitiveDataBootstrapCheck passes in the node's environment
via a constructor to bypass the shortcoming in BootstrapContext. This commit
pulls in the node's environment into BootstrapContext.

Another case is found in #36519, where it is useful to check the state of the
data-path. Since PathUtils.get and Paths.get are forbidden APIs, we rely on
the environment to retrieve references to things like node data paths.

This means that the BootstrapContext will have the same Settings used in the
Environment, which currently differs from the Node's settings.
