Core: Remove ThreadPool from base TransportAction (#31492)
Most transport actions don't need the node ThreadPool. This commit
removes the ThreadPool as a super constructor parameter for
TransportAction. The actions that do need the thread pool then have a
member added to keep it from their own constructor.

Use system context for cluster state update tasks (#31241)
This commit makes it so that cluster state update tasks always run under the system context, only
restoring the original context when the listener that was provided with the task is called. A notable
exception is the clusterStatePublished(...) callback which will still run under system context,
because it's defined on the executor-level, and not the task level, and only called once for the
combined batch of tasks and can therefore not be uniquely identified with a task / thread context.

Uncouple persistent task state and status (#31031)
This pull request removes the relationship between the state 
of persistent task (as stored in the cluster state) and the status 
of the task (as reported by the Task APIs and used in various 
places) that have been confusing for some time (#29608).

In order to do that, a new PersistentTaskState interface is added. 
This interface represents the persisted state of a persistent task. 
The methods used to update the state of persistent tasks are 
renamed: updatePersistentStatus() becomes updatePersistentTaskState() 
and now takes a PersistentTaskState as a parameter. The 
Task.Status type as been changed to PersistentTaskState in all 
places were it make sense (in persistent task customs in cluster 
state and all other methods that deal with the state of an allocated 
persistent task).

[ML] Check licence when datafeeds use cross cluster search (#31247)
This change prevents a datafeed using cross cluster search from starting if the remote cluster
does not have x-pack installed and a sufficient license. The check is made only when starting a 
datafeed.

[ML] Implement new rules design (#31110)
Rules allow users to supply a detector with domain
knowledge that can improve the quality of the results.
The model detects statistically anomalous results but it
has no knowledge of the meaning of the values being modelled.

For example, a detector that performs a population analysis
over IP addresses could benefit from a list of IP addresses
that the user knows to be safe. Then anomalous results for
those IP addresses will not be created and will not affect
the quantiles either.

Another example would be a detector looking for anomalies
in the median value of CPU utilization. A user might want
to inform the detector that any results where the actual
value is less than 5 is not interesting.

This commit introduces a `custom_rules` field to the `Detector`.
A detector may have multiple rules which are combined with `or`.

A rule has 3 fields: `actions`, `scope` and `conditions`.

Actions is a list of what should happen when the rule applies.
The current options include `skip_result` and `skip_model_update`.
The default value for `actions` is the `skip_result` action.

Scope is optional and allows for applying filters on any of the
partition/over/by field. When not defined the rule applies to
all series. The `filter_id` needs to be specified to match the id
of the filter to be used. Optionally, the `filter_type` can be specified
as either `include` (default) or `exclude`. When set to `include`
the rule applies to entities that are in the filter. When set to
`exclude` the rule only applies to entities not in the filter.

There may be zero or more conditions. A condition requires `applies_to`,
`operator` and `value` to be specified. The `applies_to` value can be
either `actual`, `typical` or `diff_from_typical` and it specifies
the numerical value to which the condition applies. The `operator`
(`lt`, `lte`, `gt`, `gte`) and `value` complete the definition.
Conditions are combined with `and` and allow to specify numerical
conditions for when a rule applies.

A rule must either have a scope or one or more conditions. Finally,
a rule with scope and conditions applies when all of them apply.

Upgrade to Netty 4.1.25.Final (#31232)
This commit upgrades us to Netty 4.1.25. This upgrade is more
challenging than past upgrades, all because of a new object cleaner
thread that they have added. This thread requires an additional security
permission (set context class loader, needed to avoid leaks in certain
scenarios). Additionally, there is not a clean way to shutdown this
thread which means that the thread can fail thread leak control during
tests. As such, we have to filter this thread from thread leak control.

Core: Remove RequestBuilder from Action (#30966)
This commit removes the RequestBuilder generic type from Action. It was
needed to be used by the newRequest method, which in turn was used by
client.prepareExecute. Both of these methods are now removed, along with
the existing users of prepareExecute constructing the appropriate
builder directly.

Use dedicated ML APIs in tests (#30941)
ML has dedicated APIs for datafeeds and jobs yet base test classes and

Only allow x-pack metadata if all nodes are ready (#30743)

Use original settings on full-cluster restart (#30780)
When doing a node restart using the test framework, the restarted node does not only use the
settings provided to the original node, but also additional settings provided by plugin extensions,
which does not correspond to the settings that a node would have on a true restart.

[ML] Don't install empty ML metadata on startup (#30751)
This change is to support rolling upgrade from a pre-6.3 default
distribution (i.e. without X-Pack) to a 6.3+ default distribution
(i.e. with X-Pack).

The ML metadata is no longer eagerly added to the cluster state
as soon as the master node has X-Pack available.  Instead, it
is added when the first ML job is created.

As a result all methods that get the ML metadata need to be able
to handle the situation where there is no ML metadata in the
current cluster state.  They do this by behaving as though an
empty ML metadata was present.  This logic is encapsulated by
always asking for the current ML metadata using a static method
on the MlMetadata class.

Hendrik Muhs 6c313a9871 This implementation lazily (on 1st forecast request) checks for available
diskspace and creates a subfolder for storing data outside of Lucene
indexes, but as part of the ES data paths.

Details:
 - tmp storage is managed and does not allow allocation if disk space is
   below a threshold (5GB at the moment)
 - tmp storage is supposed to be managed by the native component but in
   case this fails cleanup is provided:
    - on job close
    - on process crash
    - after node crash, on restart
 - available space is re-checked for every forecast call (the native
   component has to check again before writing)

Note: The 1st path that has enough space is chosen on job open (job
close/reopen triggers a new search)

[ML] Clean left behind model state docs (#30659)
It is possible for state documents to be
left behind in the state index. This may be
because of bugs or uncontrollable scenarios.
In any case, those documents may take up quite
some disk space when they add up. This commit
adds a step in the expired data deletion that
is part of the daily maintenance service. The
new step searches for state documents that
do not belong to any of the current jobs and
deletes them.

Refactors ClientHelper to combine header logic (#30620)
* Refactors ClientHelper to combine header logic

This change removes all the `*ClientHelper` classes which were
repeating logic between plugins and instead adds
`ClientHelper.executeWithHeaders()` and
`ClientHelper.executeWithHeadersAsync()` methods to centralise the
logic for executing requests with stored security headers.

[ML] Reverse engineer Grok patterns from categorization results (#30125)
This change adds a grok_pattern field to the GET categories API
output in ML. It's calculated using the regex and examples in the
categorization result, and applying a list of candidate Grok
patterns to the bits in between the tokens that are considered to
define the category.

This can currently be considered a prototype, as the Grok patterns
it produces are not optimal. However, enough people have said it
would be useful for it to be worthwhile exposing it as experimental
functionality for interested parties to try out.

[ML] Account for gaps in data counts after job is reopened (#30294)
This commit fixes an issue with the data diagnostics were
empty buckets are not reported even though they should. Once
a job is reopened, the diagnostics do not get initialized from
the current data counts (especially the latest record timestamp).
The result is that if the data that is sent have a time gap compared
to the previous ones, that gap is not accounted for in the empty bucket
count.

This commit fixes that by initializing the diagnostics with the current
data counts.

Network: Remove http.enabled setting (#29601)
This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.
