[DOCS] Add warning about bypassing ML PUT APIs (#38605)
Now that ML configurations are stored in the .ml-config
index rather than in cluster state there is a possibility
that some users may try to add configurations directly to
the index.  Allowing this creates a variety of problems
including possible data exflitration attacks (depending on
how security is set up), so this commit adds warnings
against allowing writes to the .ml-config index other than
via the ML APIs.

Align docs etc with new discovery setting names (#38492)
In #38333 and #38350 we moved away from the `discovery.zen` settings namespace
since these settings have an effect even though Zen Discovery itself is being
phased out. This change aligns the documentation and the names of related
classes and methods with the newly-introduced naming conventions.

Remove support for maxRetryTimeout from low-level REST client (#38085)
We have had various reports of problems caused by the maxRetryTimeout
setting in the low-level REST client. Such setting was initially added
in the attempts to not have requests go through retries if the request
already took longer than the provided timeout.

The implementation was problematic though as such timeout would also
expire in the first request attempt (see #31834), would leave the
request executing after expiration causing memory leaks (see #33342),
and would not take into account the http client internal queuing (see #25951).

Given all these issues, it seems that this custom timeout mechanism 
gives little benefits while causing a lot of harm. We should rather rely 
on connect and socket timeout exposed by the underlying http client 
and accept that a request can overall take longer than the configured 
timeout, which is the case even with a single retry anyways.

This commit removes the `maxRetryTimeout` setting and all of its usages.

Remove support for internal versioning for concurrency control (#38254)
Elasticsearch has long [supported](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-index_.html#index-versioning) compare and set (a.k.a optimistic concurrency control) operations using internal document versioning. Sadly that approach is flawed and can sometime do the wrong thing. Here's the relevant excerpt from the resiliency status page:

> When a primary has been partitioned away from the cluster there is a short period of time until it detects this. During that time it will continue indexing writes locally, thereby updating document versions. When it tries to replicate the operation, however, it will discover that it is partitioned away. It won’t acknowledge the write and will wait until the partition is resolved to negotiate with the master on how to proceed. The master will decide to either fail any replicas which failed to index the operations on the primary or tell the primary that it has to step down because a new primary has been chosen in the meantime. Since the old primary has already written documents, clients may already have read from the old primary before it shuts itself down. The version numbers of these reads may not be unique if the new primary has already accepted writes for the same document 

We recently [introduced](https://www.elastic.co/guide/en/elasticsearch/reference/6.x/optimistic-concurrency-control.html) a new sequence number based approach that doesn't suffer from this dirty reads problem. 

This commit removes support for internal versioning as a concurrency control mechanism in favor of the sequence number approach.

Make sure to reject mappings with type _doc when include_type_name is false. (#38270)
`CreateIndexRequest#source(Map<String, Object>, ... )`, which is used when
deserializing index creation requests, accidentally accepts mappings that are
nested twice under the type key (as described in the bug report #38266).

This in turn causes us to be too lenient in parsing typeless mappings. In
particular, we accept the following index creation request, even though it
should not contain the type key `_doc`:

```
PUT index?include_type_name=false
{
  "mappings": {
    "_doc": {
      "properties": { ... }
    }
  }
}
```

There is a similar issue for both 'put templates' and 'put mappings' requests
as well.

This PR makes the minimal changes to detect and reject these typed mappings in
requests. It does not address #38266 generally, or attempt a larger refactor
around types in these server-side requests, as I think this should be done at a
later time.

Remove DiscoveryPlugin#getDiscoveryTypes (#38414)
With this change we no longer support pluggable discovery implementations. No
known implementations of `DiscoveryPlugin` actually override this method, so in
practice this should have no effect on the wider world. However, we were using
this rather extensively in tests to provide the `test-zen` discovery type. We
no longer need a separate discovery type for tests as we no longer need to
customise its behaviour.

Add support for API keys to access Elasticsearch (#38291)
X-Pack security supports built-in authentication service
`token-service` that allows access tokens to be used to 
access Elasticsearch without using Basic authentication.
The tokens are generated by `token-service` based on
OAuth2 spec. The access token is a short-lived token
(defaults to 20m) and refresh token with a lifetime of 24 hours,
making them unsuitable for long-lived or recurring tasks where
the system might go offline thereby failing refresh of tokens.

This commit introduces a built-in authentication service
`api-key-service` that adds support for long-lived tokens aka API
keys to access Elasticsearch. The `api-key-service` is consulted
after `token-service` in the authentication chain. By default,
if TLS is enabled then `api-key-service` is also enabled.
The service can be disabled using the configuration setting.

The API keys:-
- by default do not have an expiration but expiration can be
  configured where the API keys need to be expired after a
  certain amount of time.
- when generated will keep authentication information of the user that
   generated them.
- can be defined with a role describing the privileges for accessing
   Elasticsearch and will be limited by the role of the user that
   generated them
- can be invalidated via invalidation API
- information can be retrieved via a get API
- that have been expired or invalidated will be retained for 1 week
  before being deleted. The expired API keys remover task handles this.

Following are the API key management APIs:-
1. Create API Key - `PUT/POST /_security/api_key`
2. Get API key(s) - `GET /_security/api_key`
3. Invalidate API Key(s) `DELETE /_security/api_key`

The API keys can be used to access Elasticsearch using `Authorization`
header, where the auth scheme is `ApiKey` and the credentials, is the 
base64 encoding of API key Id and API key separated by a colon.
Example:-
```
curl -H "Authorization: ApiKey YXBpLWtleS1pZDphcGkta2V5" http://localhost:9200/_cluster/health
```

Add nanosecond field mapper (#37755)
This adds a dedicated field mapper that supports nanosecond resolution -
at the price of a reduced date range.

When using the date field mapper, the time is stored as milliseconds since the epoch
in a long in lucene. This field mapper stores the time in nanoseconds
since the epoch - which means its range is much smaller, ranging roughly from
1970 to 2262.

Note that aggregations will still be in milliseconds.
However docvalue fields will have full nanosecond resolution

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.

Add finalReduce flag to SearchRequest (#38104)
With #37000 we made sure that fnial reduction is automatically disabled
whenever a localClusterAlias is provided with a SearchRequest.

While working on #37838, we found a scenario where we do need to set a
localClusterAlias yet we would like to perform a final reduction in the
remote cluster: when searching on a single remote cluster.

Relates to #32125

This commit adds support for a separate finalReduce flag to
SearchRequest and makes use of it in TransportSearchAction in case we
are searching against a single remote cluster.

This also makes sure that num_reduce_phases is correct when searching
against a single remote cluster: it makes little sense to return
`num_reduce_phases` set to `2`, which looks especially weird in case
the search was performed against a single remote shard. We should
perform one reduction phase only in this case and `num_reduce_phases`
should reflect that.

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.

Give precedence to index creation when mixing typed templates with typeless index creation and vice-versa. (#37871)
Currently if you mix typed templates and typeless index creation or typeless
templates and typed index creation then you will end up with an error because
Elasticsearch tries to create an index that has multiple types: `_doc` and
the explicit type name that you used.

This commit proposes to give precedence to the index creation call so that
the type from the template will be ignored if the index creation call is
typeless while the template is typed, and the type from the index creation
call will be used if there is a typeless template.

This is consistent with the fact that index creation already "wins" if a field
is defined differently in the index creation call and in a template: the
definition from the index creation call is used in such cases.

Remove implicit index monitor privilege (#37774)
Restricted indices (currently only .security-6 and .security) are special
internal indices that require setting the `allow_restricted_indices` flag
on every index permission that covers them. If this flag is `false`
(default) the permission will not cover these and actions against them
will not be authorized.
However, the monitoring APIs were the only exception to this rule.

This exception is herein forfeited and index monitoring privileges have to be
granted explicitly, using the `allow_restricted_indices` flag on the permission,
as is the case for any other index privilege.

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.

Inject Unfollow before Rollover and Shrink (#37625)
We inject an Unfollow action before Shrink because the Shrink action
cannot be safely used on a following index, as it may not be fully
caught up with the leader index before the "original" following index is
deleted and replaced with a non-following Shrunken index. The Unfollow
action will verify that 1) the index is marked as "complete", and 2) all
operations up to this point have been replicated from the leader to the
follower before explicitly disconnecting the follower from the leader.

Injecting an Unfollow action before the Rollover action is done mainly
as a convenience: This allow users to use the same lifecycle policy on
both the leader and follower cluster without having to explictly modify
the policy to unfollow the index, while doing what we expect users to
want in most cases.

Support both typed and typeless 'get mapping' requests in the HLRC. (#37796)
From previous PRs, we've already added support for include_type_name to
the get mapping API. We had also taken an approach to the HLRC where the
server-side `GetMappingResponse#fromXContent` could only handle typeless
input.

This PR updates the HLRC for 'get mapping' to be in line with our new approach:

* Add a typeless 'get mappings' method to the Java HLRC, that accepts new
client-side request and response objects. This new response only handles
typeless mapping definitions.
* Switch the old version of `GetMappingResponse` back to expecting typed
mappings, and deprecate the corresponding method on the HLRC.

Finally, the PR also does some small, related clean-up around 'get field mappings'.

The ML file structure finder has always reported both Joda

The BWC syntax of prepending "8" to these formats is used.

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.

Remove index audit output type (#37707)
This commit removes the Index Audit Output type, following its deprecation
in 6.7 by 8765a31d4e6770. It also adds the migration notice (settings notice).

In general, the problem with the index audit output is that event indexing
can be slower than the rate with which audit events are generated,
especially during the daily rollovers or the rolling cluster upgrades.
In this situation audit events will be lost which is a terrible failure situation
for an audit system.
Besides of the settings under the `xpack.security.audit.index` namespace, the
`xpack.security.audit.outputs` setting has also been deprecated and will be
removed in 7. Although explicitly configuring the logfile output does not touch
any deprecation bits, this setting is made redundant in 7 so this PR deprecates
it as well.

Martijn van Groningen a3030c51e2 [ILM] Add unfollow action (#36970)
This change adds the unfollow action for CCR follower indices.

This is needed for the shrink action in case an index is a follower index.
This will give the follower index the opportunity to fully catch up with
the leader index, pause index following and unfollow the leader index.
After this the shrink action can safely perform the ilm shrink.

The unfollow action needs to be added to the hot phase and acts as
barrier for going to the next phase (warm or delete phases), so that
follower indices are being unfollowed properly before indices are expected
to go in read-only mode. This allows the force merge action to execute
its steps safely.

The unfollow action has three steps:
* `wait-for-indexing-complete` step: waits for the index in question
  to get the `index.lifecycle.indexing_complete` setting be set to `true`
* `wait-for-follow-shard-tasks` step: waits for all the shard follow tasks
  for the index being handled to report that the leader shard global checkpoint
  is equal to the follower shard global checkpoint.
* `pause-follower-index` step: Pauses index following, necessary to unfollow
* `close-follower-index` step: Closes the index, necessary to unfollow
* `unfollow-follower-index` step: Actually unfollows the index using 
  the CCR Unfollow API
* `open-follower-index` step: Reopens the index now that it is a normal index
* `wait-for-yellow` step: Waits for primary shards to be allocated after
  reopening the index to ensure the index is ready for the next step

In the case of the last two steps, if the index in being handled is
a regular index then the steps acts as a no-op.
