This change adds either ToXContentObject or ToXContentFragment to classes
directly implementing ToXContent currently. This helps in reasoning about
whether those implementations output full xcontent object or just fragments.

* moved hlrc parsing tests from xpack to hlrc module and removed dependency on hlrc from xpack core
* deprecated old base test class
* added deprecated jdoc tag
* split test between xpack-core part and hlrc part
* added lang-mustache test dependency, this previously came in via
hlrc dependency.
* added hlrc dependency on a qa module
* duplicated ClusterPrivilegeName class in xpack-core, since x-pack
core no longer has a dependency on hlrc.
* replace ClusterPrivilegeName usages with string literals
* moved tests to dedicated to hlrc packages in order to remove Hlrc part from the name and make sure to use imports instead of full qualified class where possible
* remove ESTestCase. from method invocation and use method directly,
because these tests indirectly extend from ESTestCase
changed hlrc ccr request tests to use AbstractRequestTestCase base class.
This way the request classes are tested in a more realistic setting.
Note this change also adds a test dependency on xpack core module.
Similar to #39844 but then for hlrc request serialization tests.
Removed iterators from hlrc parsing tests.
Use empty xcontent registries.

Made changes to ensure that unique IDs are generated for model snapshots
used by the deleteExpiredDataTest test in the MachineLearningIT suite.
Previously a sleep of 1s was performed between jobs under the assumption
that this would be sufficient to guarantee that the timestamps used in
the composition of the snapshot IDs would be different.
The new approach is to wait on the condition that the old and new
timestamps are in fact different (to 1s resolution).
This commit fixes a problem with BWC that was brought up in #40511. A
newer version of the code was emitting a new value for an enum to an
older version, and the older version could not handle that. It caused
the response to error. The MainResponse is now relaxed, and will accept
whatever values the server expose, and holds most of them as Strings
instead of complex objects.
Fixes#40511
This adds a new `role_templates` field to role mappings that is an
alternative to the existing roles field.
These templates are evaluated at runtime to determine which roles should be
granted to a user.
For example, it is possible to specify:
"role_templates": [
{ "template":{ "source": "_user_{{username}}" } }
]
which would mean that every user is assigned to their own role based on
their username.
You may not specify both roles and role_templates in the same role
mapping.
This commit adds support for templates to the role mapping API, the role
mapping engine, the Java high level rest client, and Elasticsearch
documentation.
Due to the lack of caching in our role mapping store, it is currently
inefficient to use a large number of templated role mappings. This will be
addressed in a future change.

It initially mentioned the type in the exception because the type used to be
required to uniquely identify a document. This is not necessary anymore given
that indices have at most one type.
The reindex family of APIs (reindex, update-by-query, delete-by-query) can
sometimes return responses that have an error status code (409 Conflict in this
case) but still have a body in the usual BulkByScrollResponse format. When the
HLRC tries to handle such responses, it blows up because it tris to parse it
expecting the error format that errors in general use. This change prompts the
HLRC to parse the response using the expected BulkByScrollResponse format.

The base class facilitates generating a server side response test instance,
that gets serialized as xcontent, which then gets parsed into a hlrc response
instance, which then gets asserted against the server side response instance.
This way of testing is more realistic then how hlrc response classes are tested
today, which basically tests that serialization works by generating
hlrc response instance, serialize that to xcontent and then parse it back
to a hlrc response instance.
Besides adding a base test class, this change also cuts AcknowledgedResponseTests
and BroadcastResponseTests over to use this base class.

The Migration Assistance API has been functionally replaced by the
Deprecation Info API, and the Migration Upgrade API is not used for the
transition from ES 6.x to 7.x, and does not need to be kept around to
repair indices that were not properly upgraded before upgrading the
cluster, as was the case in 6.
This PR adds an internal REST API for querying context information about
Painless whitelists.
Commands include the following:
GET /_scripts/painless/_context -- retrieves a list of contexts
GET /_scripts/painless/_context?context=%name% retrieves all available
information about the API for this specific context
As discovered in #40041, when parsing certificates from files, the
SUN Security Provider normalizes DNs from parsed certificates by
adding spaces between RDNs, while the BouncyCastle one (which we
use in FIPS tests) does not.
We could proceed to normalize the DNs in the same manner in this
test by using i.e. the Unbound LDAP SDK but since the goal of this
test is to validate that we do get to read these exact certificates
from our trust sources and not to validate subject DNs, this commit
changes the test to check the serial number instead
Resolves: #40041
The monitoring bulk API accepts the same format as the bulk API, yet its concept
of types is different from "mapping types" and the deprecation warning is only
emitted as a side-effect of this API reusing the parsing logic of bulk requests.
This commit extracts the parsing logic from `_bulk` into its own class with a
new flag that allows to configure whether usage of `_type` should emit a warning
or not. Support for payloads has been removed for simplicity since they were
unused.
@jakelandis has a separate change that removes this notion of type from the
monitoring bulk API that we are considering bringing to 8.0.
This commit introduces the forget follower API. This API is needed in cases that
unfollowing a following index fails to remove the shard history retention leases
on the leader index. This can happen explicitly through user action, or
implicitly through an index managed by ILM. When this occurs, history will be
retained longer than necessary. While the retention lease will eventually
expire, it can be expensive to allow history to persist for that long, and also
prevent ILM from performing actions like shrink on the leader index. As such, we
introduce an API to allow for manual removal of the shard history retention
leases in this case.
This change adds two new cluster privileges:
* manage_data_frame_transforms
* monitor_data_frame_transforms
And two new built-in roles:
* data_frame_transforms_admin
* data_frame_transforms_user
These permit access to the data frame transform endpoints.
(Index privileges are also required on the source and
destination indices for each data frame transform, but
since these indices are configurable they it is not
appropriate to grant them via built-in roles.)
The data frame plugin allows users to create feature indexes by pivoting a source index. In a
nutshell this can be understood as reindex supporting aggregations or similar to the so called entity
centric indexing.

Updated IndexTemplateMetaData to use ObjectParser.
The IndexTemplateMetaData class used old parsing logic and was not
resiliant to new fields. This commit updates it to use the
ConstructingObjectParser and allow unknown fields.

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.

`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.
This PR fixes a couple test issues:
* It narrows an assertWarnings call that was too broad, and wasn't always
applicable with certain random sequences.
* Previously, we could send a typeless bulk request containing '_type: 'null'.
Now we omit the _type key altogether for typeless requests.
This commit ensures that the parts of rollup caps that can allow unknown
fields will allow them. It also modifies the test such that we can use
the features we need for disallowing fields in spots where they would
not be allowed.

Introduced FollowParameters class that put follow, resume follow,
put auto follow pattern requests and follow info response classes reuse.
The FollowParameters class had the fields, getters etc. for the common parameters
that all these APIs have. Also binary and xcontent serialization /
parsing is handled by this class.
The follow, resume follow, put auto follow pattern request classes originally
used optional non primitive fields, so FollowParameters has that too and the follow info api can handle that now too.
Also the followerIndex field can in production only be specified via
the url path. If it is also specified via the request body then
it must have the same value as is specified in the url path. This
option only existed to xcontent testing. However the AbstractSerializingTestCase
base class now also supports createXContextTestInstance() to provide
a different test instance when testing xcontent, so allowing followerIndex
to be specified via the request body is no longer needed.
By moving the followerIndex field from Body to ResumeFollowAction.Request
class and not allowing the followerIndex field to be specified via
the request body the Body class is redundant and can be removed. The
ResumeFollowAction.Request class can then directly use the
FollowParameters class.
For consistency I also removed the ability to specified followerIndex
in the put follow api and the name in put auto follow pattern api via
the request body.

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
```
