Watcher: Reenable HttpSecretsIntegrationTests#testWebhookAction test (#32456)
The error message mentioned in #30094 does not link to to a cause by the
test itself, as there are still inflight requests according to the
circuit breaker.

I ran this test class 100k times on bare metal and could not reproduce
it. I will reenable the test for now.

[Rollup] Remove builders from TermsGroupConfig (#32507)
While working on adding the Create Rollup Job API to the 
high level REST client (#29827), I noticed that the configuration 
objects like TermsGroupConfig rely on the Builder pattern in 
order to create or parse instances. These builders are doing 
some validation but the same validation could be done within 
the constructor itself or on the server side when appropriate.

This commit removes the builder for TermsGroupConfig, 
removes some other methods that I consider not really usefull 
once the TermsGroupConfig object will be exposed in the 
high level REST client. It also simplifies the parsing logic.

NETWORKING: Fix Netty Leaks by upgrading to 4.1.28 (#32511)
* Upgrade to `4.1.28` since the problem reported in #32487 is a bug in Netty itself (see https://github.com/netty/netty/issues/7337)
* Fixed other leaks in test code that now showed up due to fixes improvements in leak reporting in the newer version
* Needed to extend permissions for netty common package because it now sets a classloader at runtime after changes in 63bae0956a
* Adjusted forbidden APIs check accordingly
* Closes #32487

Add licensing enforcement for FIPS mode (#32437)
This commit adds licensing enforcement for FIPS mode through the use of
a bootstrap check, a node join validator, and a check in the license
service. The work done here is based on the current implementation of
the TLS enforcement with a production license.

The bootstrap check is always enforced since we need to enforce the
licensing and this is the best option to do so at the present time.

Logging: Make node name consistent in logger (#31588)
First, some background: we have 15 different methods to get a logger in
Elasticsearch but they can be broken down into three broad categories
based on what information is provided when building the logger.

Just a class like:
```
private static final Logger logger = ESLoggerFactory.getLogger(ActionModule.class);
```
or:
```
protected final Logger logger = Loggers.getLogger(getClass());
```

The class and settings:
```
this.logger = Loggers.getLogger(getClass(), settings);
```

Or more information like:
```
Loggers.getLogger("index.store.deletes", settings, shardId)
```

The goal of the "class and settings" variant is to attach the node name
to the logger. Because we don't always have the settings available, we
often use the "just a class" variant and get loggers without node names
attached. There isn't any real consistency here. Some loggers get the
node name because it is convenient and some do not.

This change makes the node name available to all loggers all the time.
Almost. There are some caveats are testing that I'll get to. But in
*production* code the node name is node available to all loggers. This
means we can stop using the "class and settings" variants to fetch
loggers which was the real goal here, but a pleasant side effect is that
the ndoe name is now consitent on every log line and optional by editing
the logging pattern. This is all powered by setting the node name
statically on a logging formatter very early in initialization.

Now to tests: tests can't set the node name statically because
subclasses of `ESIntegTestCase` run many nodes in the same jvm, even in
the same class loader. Also, lots of tests don't run with a real node so
they don't *have* a node name at all. To support multiple nodes in the
same JVM tests suss out the node name from the thread name which works
surprisingly well and easy to test in a nice way. For those threads
that are not part of an `ESIntegTestCase` node we stick whatever useful
information we can get form the thread name in the place of the node
name. This allows us to keep the logger format consistent.

[Kerberos] Remove Kerberos bootstrap checks (#32451)
This commit removes Kerberos bootstrap checks as they were more
validation checks and better done in Kerberos realm constructor
than as bootstrap checks. This also moves the check
for one Kerberos realm per node to where we initialize realms.
This commit adds few validations which were missing earlier
like missing read permissions on keytab file or if it is directory
to throw exception with error message.

ShardFollowNodeTask should fetch operation once (#32455)
Today ShardFollowNodeTask might fetch some operations more than once.
This happens because we ask the leading for up to max_batch_count
operations (instead of the left-over size) for the left-over request.
The leading then can freely respond up to the max_batch_count, and at
the same time, if one of the previous requests completed, we might issue
another read request whose range overlaps with the response of the
left-over request.

Today we do not check if the `following_index` setting of the follower

disabled, the follower will use the default engine, not the following
engine. This change checks and rejects such invalid follow requests.

Validate source of an index in LuceneChangesSnapshot (#32288)
Today it's possible to encounter an Index operation in Lucene whose
_source is disabled, and _recovery_source was pruned by the MergePolicy.
If it's the case, we create a Translog#Index without source and let the
caller validate it later. However, this approach is challenging for the
caller.

Deletes and No-Ops don't allow invoking "source()" method. The caller
has to make sure to call "source()" only on index operations. The
current implementation in CCR does not follow this and fail to replica
deletes or no-ops. Moreover, it's easier to reason if a Translog#Index
always has the source.

[ML] Consistent pattern for strict/lenient parser names (#32399)
Previously we had two patterns for naming of strict
and lenient parsers.

Some classes had CONFIG_PARSER and METADATA_PARSER,
and used an enum to pass the parser type to nested
parsers.

Other classes had STRICT_PARSER and LENIENT_PARSER
and used ternary operators to pass the parser type
to nested parsers.

This change makes all ML classes use the second of
the patterns described above.

Introduce index store plugins (#32375)
Today we allow plugins to add index store implementations yet we are not
doing this in our new way of managing plugins as pull versus push. That
is, today we still allow plugins to push index store providers via an on
index module call where they can turn around and add an index
store. Aside from being inconsistent with how we manage plugins today
where we would look to pull such implementations from plugins at node
creation time, it also means that we do not know at a top-level (for
example, in the indices service) which index stores are available. This
commit addresses this by adding a dedicated plugin type for index store
plugins, removing the index module hook for adding index stores, and by
aggregating these into the top-level of the indices service.

Security: revert to old way of merging automata (#32254)
This commit reverts to the pre-6.3 way of merging automata as the
change in 6.3 significantly impacts the performance for roles with a
large number of concrete indices. In addition, the maximum number of
states for security automata has been increased to 100,000 in order
to allow users to use roles that caused problems pre-6.3 and 6.3 fixed.

As an escape hatch, the maximum number of states is configurable with
a setting so that users with complex patterns in roles can increase
the states with the knowledge that there is more memory usage.

387c3c7f1d Introduce Application Privileges with support for Kibana RBAC (#32309)
This commit introduces "Application Privileges" to the X-Pack security
model.

Application Privileges are managed within Elasticsearch, and can be
tested with the _has_privileges API, but do not grant access to any
actions or resources within Elasticsearch. Their purpose is to allow
applications outside of Elasticsearch to represent and store their own
privileges model within Elasticsearch roles.

Access to manage application privileges is handled in a new way that
grants permission to specific application names only. This lays the
foundation for more OLS on cluster privileges, which is implemented by
allowing a cluster permission to inspect not just the action being
executed, but also the request to which the action is applied.
To support this, a "conditional cluster privilege" is introduced, which
is like the existing cluster privilege, except that it has a Predicate
over the request as well as over the action name.

Specifically, this adds
- GET/PUT/DELETE actions for defining application level privileges
- application privileges in role definitions
- application privileges in the has_privileges API
- changes to the cluster permission class to support checking of request
  objects
- a new "global" element on role definition to provide cluster object
  level security (only for manage application privileges)
- changes to `kibana_user`, `kibana_dashboard_only_user` and
  `kibana_system` roles to use and manage application privileges

Build: Shadow x-pack:protocol into x-pack:plugin:core (#32240)
This bundles the x-pack:protocol project into the x-pack:plugin:core
project because we'd like folks to consider it an implementation detail
of our build rather than a separate artifact to be managed and depended
on. It is now bundled into both x-pack:plugin:core and
client:rest-high-level. To make this work I had to fix a few things.

Firstly, I had to make PluginBuildPlugin work with the shadow plugin.
In that case we have to bundle only the `shadow` dependencies and the
shadow jar.

Secondly, every reference to x-pack:plugin:core has to use the `shadow`
configuration. Without that the reference is missing all of the
un-shadowed dependencies. I tried to make it so that applying the shadow
plugin automatically redefines the `default` configuration to mirror the
`shadow` configuration which would allow us to use bare project references
to the x-pack:plugin:core project but I couldn't make it work. It'd *look*
like it works but then fail for transitive dependencies anyway. I think
it is still a good thing to do but I don't have the willpower to do it
now.

Finally, I had to fix an issue where Eclipse and IntelliJ didn't properly
reference shadowed transitive dependencies. Neither IDE supports shadowing
natively so they have to reference the shadowed projects. We fix this by
detecting `shadow` dependencies when in "Intellij mode" or "Eclipse mode"
and adding `runtime` dependencies to the same target. This convinces
IntelliJ and Eclipse to play nice.

a525c36c60 [Kerberos] Add Kerberos authentication support (#32263)
This commit adds support for Kerberos authentication with a platinum
license. Kerberos authentication support relies on SPNEGO, which is
triggered by challenging clients with a 401 response with the
`WWW-Authenticate: Negotiate` header. A SPNEGO client will then provide
a Kerberos ticket in the `Authorization` header. The tickets are
validated using Java's built-in GSS support. The JVM uses a vm wide
configuration for Kerberos, so there can be only one Kerberos realm.
This is enforced by a bootstrap check that also enforces the existence
of the keytab file.

In many cases a fallback authentication mechanism is needed when SPNEGO
authentication is not available. In order to support this, the
DefaultAuthenticationFailureHandler now takes a list of failure response
headers. For example, one realm can provide a
`WWW-Authenticate: Negotiate` header as its default and another could
provide `WWW-Authenticate: Basic` to indicate to the client that basic
authentication can be used in place of SPNEGO.

In order to test Kerberos, unit tests are run against an in-memory KDC
that is backed by an in-memory ldap server. A QA project has also been
added to test against an actual KDC, which is provided by the krb5kdc
fixture.

Add WeightedAvg metric aggregation (#31037)
Adds a new single-value metrics aggregation that computes the weighted 
average of numeric values that are extracted from the aggregated 
documents. These values can be extracted from specific numeric
fields in the documents.

When calculating a regular average, each datapoint has an equal "weight"; it
contributes equally to the final value.  In contrast, weighted averages
scale each datapoint differently.  The amount that each datapoint contributes 
to the final value is extracted from the document, or provided by a script.

As a formula, a weighted average is the `∑(value * weight) / ∑(weight)`

A regular average can be thought of as a weighted average where every value has
an implicit weight of `1`.

Switch monitoring to new style Requests (#32255)
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `x-pack/plugin/monitoring` project to use the new
versions.
