Remove script engine from X-Pack plugin (#41387)
The X-Pack plugin implements ScriptEngine yet it does not actually
implement any of the methods on the interface, effectively making this a
no-op. This commit removes this interface from the X-Pack plugin.

Extract template management from Watcher (#41169)
This commit extracts the template management from Watcher into an
abstract class, so that templates and lifecycle policies can be managed
in the same way across multiple plugins. This will be useful for SLM, as
well as potentially ILM and any other plugins which need to manage index
templates.

Zachary Tong 7e62ff2823 [Rollup] Validate timezones based on rules not string comparision (#36237)
The date_histogram internally converts obsolete timezones (such as
"Canada/Mountain") into their modern equivalent ("America/Edmonton").
But rollup just stored the TZ as provided by the user.

When checking the TZ for query validation we used a string comparison,
which would fail due to the date_histo's upgrading behavior.

Instead, we should convert both to a TimeZone object and check if their
rules are compatible.

Expand beats_system role privileges (#40876) (#41232)
Traditionally we have [recommended](https://www.elastic.co/guide/en/beats/filebeat/current/monitoring.html) that Beats send their monitoring data to the **production** Elasticsearch cluster. Beats do this by calling the `POST _monitoring/bulk` API. When Security is enabled this API call requires the `cluster:admin/xpack/monitoring/bulk` privilege. The built-in `beats_system` role has this privilege.

[Going forward](https://github.com/elastic/beats/pull/9260), Beats will be able to send their monitoring data directly to the **monitoring** Elasticsearch cluster. Beats will do this by calling the regular `POST _bulk` API. When Security is enabled this API call requires the `indices:data/write/bulk` privilege. Further, the call has to be able to create any indices that don't exist.

This PR expands the built-in `beats_system` role's privileges. Specifically, it adds index-level `write` and `create_index` privileges for `.monitoring-beats-*` indices. 

This will allow Beats users to continue using the `beats_system` role for the new direct monitoring route when Security is enabled.

Remove xpack dependencies from qa rest modules (#41134) (7.x backport) (#41202)
This commit removes xpack dependencies of many xpack qa modules.
(for some qa modules this will require some more work)

The reason behind this change is that qa rest modules should not depend
on the x-pack plugins, because the plugins are an implementation detail and
the tests should only know about the rest interface and qa cluster that is
being tested.

Also some qa modules rely on xpack plugins and hlrc (which is a valid
dependency for rest qa tests) creates a cyclic dependency and this is
something that we should avoid.  Also Eclipse can't handle gradle cyclic
dependencies (see #41064).

* don't copy xpack-core's plugin property into the test resource of qa
modules. Otherwise installing security manager fails, because it tries
to find the XPackPlugin class.

Add an OpenID Connect authentication realm (#40674) (#41178)
This commit adds an OpenID Connect authentication realm to
elasticsearch. Elasticsearch (with the assistance of kibana or
another web component) acts as an OpenID Connect Relying
Party and supports the Authorization Code Grant and Implicit
flows as described in http://ela.st/oidc-spec. It adds support
for consuming and verifying signed ID Tokens, both RP
initiated and 3rd party initiated Single Sign on and RP
initiated signle logout.
It also adds an OpenID Connect Provider in the idp-fixture to
be used for the associated integration tests.

This is a backport of #40674

(7.x) Use environment settings instead of state settings for Watcher config (#41158)
Backport of (#41087)

* Use environment settings instead of state settings for Watcher config

Prior to this we used the settings from cluster state to see whether ILM was
enabled of disabled, however, these settings don't accurately reflect the
`xpack.ilm.enabled` setting in `elasticsearch.yml`.

This commit changes to using the `Environment` settings, which correctly reflect
the ILM enabled setting.

Deprecate AbstractHlrc* and AbstractHlrcStreamable* base test classes (#41014)
* 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

Deprecate permission over aliases (#38059) (#41060)
This PR generates deprecation log entries for each Role Descriptor,
used for building a Role, when the Role Descriptor grants more privileges
for an alias compared to an index that the alias points to. This is done in
preparation for the removal of the ability to define privileges over aliases.
There is one log entry for each "role descriptor name"-"alias name" pair.
On such a notice, the administrator is expected to modify the Role Descriptor
definition so that the name pattern for index names does not cover aliases.

Caveats:
* Role Descriptors that are not used in any authorization process,
either because they are not mapped to any user or the user they are mapped to
is not used by clients, are not be checked.
* Role Descriptors are merged when building the effective Role that is used in
the authorization process. Therefore some Role Descriptors can overlap others,
so even if one matches aliases in a deprecated way, and it is reported as such,
it is not at risk from the breaking behavior in the current role mapping configuration
and index-alias configuration. It is still reported because it is a best practice to
change its definition, or remove offending aliases.

[Backport] Replace usages RandomizedTestingTask with built-in Gradle Test (#40978) (#40993)
* Replace usages RandomizedTestingTask with built-in Gradle Test (#40978)

This commit replaces the existing RandomizedTestingTask and supporting code with Gradle's built-in JUnit support via the Test task type. Additionally, the previous workaround to disable all tasks named "test" and create new unit testing tasks named "unitTest" has been removed such that the "test" task now runs unit tests as per the normal Gradle Java plugin conventions.

Remove dynamic objects from security index (#40715)
The security index had a few "object" types with

   "dynamic": true

However, this automatically creates a mapping for each field that is
created within those objects. This means that types are dynamically
inferred and "locked in" for future updates.

Instead we want "dynamic": false which will allow us to store a range
of fields in these nested objects and retrieve them from the source,
without creating mapping types for those fields.

Make -try xlint warning disabled by default. (#40833)
Many gradle projects specifically use the -try exclude flag, because
there are many cases where auto-closeable resource ignore is never
referenced in body of corresponding try statement. Suppressing this
warning specifically in each case that it happens using
`@SuppressWarnings("try")` would be very verbose.

This change removes `-try` from any gradle project and adds it to the
build plugin. Also this change removes exclude flags from gradle projects
that is already specified in build plugin (for example -deprecation).

David Roberts d16f86f7ab [ML] Add created_by info to usage stats (#40518)
This change adds information about which UI path
(if any) created ML anomaly detector jobs to the
stats returned by the _xpack/usage endpoint.

Counts for the following possibilities are expected:

* ml_module_apache_access
* ml_module_apm_transaction
* ml_module_auditbeat_process_docker
* ml_module_auditbeat_process_hosts
* ml_module_nginx_access
* ml_module_sample
* multi_metric_wizard
* population_wizard
* single_metric_wizard
* unknown

The "unknown" count is for jobs that do not have a
created_by setting in their custom_settings.

Show SSL usage when security is not disabled (#40761)
It is possible to have SSL enabled but security disabled if security
was dynamically disabled by the license type (e.g. trial license).

e.g. In the following configuration:

    xpack.license.self_generated.type: trial
    # xpack.security not set, default to disabled on trial
    xpack.security.transport.ssl.enabled: true

The security feature will be reported as

    available: true
    enabled: false

And in this case, SSL will be active even though security is not
enabled.

This commit causes the X-Pack feature usage to report the state of the
"ssl" features unless security was explicitly disabled in the
settings.

Support mustache templates in role mappings (#40571)
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.

Support roles with application privileges against wildcard applications (#40675)
This commit introduces 2 changes to application privileges:

- The validation rules now accept a wildcard in the "suffix" of an application name.
  Wildcards were always accepted in the application name, but the "valid filename" check
  for the suffix incorrectly prevented the use of wildcards there.

- A role may now be defined against a wildcard application (e.g. kibana-*) and this will
  be correctly treated as granting the named privileges against all named applications.
  This does not allow wildcard application names in the body of a "has-privileges" check, but the
  "has-privileges" check can test concrete application names against roles with wildcards.

Hendrik Muhs 5a0c32833e Add a checkpoint service for data frame transforms (#39836)
Add a checkpoint service for data frame transforms, which allows to ask for a checkpoint of the

 - updating the data frame without a full re-run
 - allow data frame clients to checkpoint themselves
