Deprecate /_xpack/security/* in favor of /_security/* (#36293)
* This commit is part of our plan to deprecate and ultimately remove the use of _xpack in the REST APIs.

- REST API docs
- HLRC docs and doc tests
- Handle REST actions with deprecation warnings
- Changed endpoints in rest-api-spec and relevant file names

Core: Converge FormatDateTimeFormatter and DateFormatter apis (#36390)
This commit makes FormatDateTimeFormatter and DateFormatter apis close
to each other, so that the former can be removed in favor of the latter.
This PR does not change the uses of FormatDateTimeFormatter yet, so that
that future change can be purely mechanical.

[ML] Move consuming and closing results stream to result processor (#36314)
The results iterator is consuming and closing the results stream
once it is done. It seems this should not be the responsibility
of the results iterator. It stops the iterator from being reusable
for different processes where closing the stream is not desirable.
This commit is moving the consuming and closing of the results stream
into the autodetect result processor.

Make hits.total an object in the search response (#35849)
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

Core: Less settings to AbstractComponent (#35140)
Stop passing `Settings` to `AbstractComponent`'s ctor. This allows us to
stop passing around `Settings` in a *ton* of places. While this change
touches many files, it touches them all in fairly small, mechanical
ways, doing a few things per file:
1. Drop the `super(settings);` line on everything that extends
`AbstractComponent`.
2. Drop the `settings` argument to the ctor if it is no longer used.
3. If the file doesn't use `logger` then drop `extends
AbstractComponent` from it.
4. Clean up all compilation failure caused by the `settings` removal
and drop any now unused `settings` isntances and method arguments.

I've intentionally *not* removed the `settings` argument from a few
files:
1. TransportAction
2. AbstractLifecycleComponent
3. BaseRestHandler

These files don't *need* `settings` either, but this change is large
enough as is.

Pre-populate unicast hosts files (#35136)
Today when ESIntegTestCase starts some nodes it writes out the unicast hosts
files each time a node starts its transport service. This does mean that a
number of nodes can start and perform their first pinging round without any
unicast hosts which, if the timing is unlucky and a lot of nodes are all
started at the same time, can lead to a split brain as in #35052.

Prior to #33554 this was unlikely to happen since the MockUncasedHostsProvider
would always have yielded the existing hosts, so the timing would have to have
been implausibly unlucky. Since #33554, however, it's more likely because the
race occurs between the start of the first round of pinging and the writing of
the unicast hosts file. It is realistic that new nodes will be configured with
the existing nodes from startup, so this change reinstates that behaviour.

Closes #35052.

Core: Drop settings member from AbstractComponent (#35083)
Drops the `Settings` member from `AbstractComponent`, moving it from the
base class on to the classes that use it. For the most part this is a
mechanical change that doesn't drop `Settings` accesses. The one
exception to this is naming threads where it switches from an invocation
that passes `Settings` and extracts the node name to one that explicitly
passes the node name.

This change doesn't drop the `Settings` argument from
`AbstractComponent`'s ctor because this change is big enough as is.
We'll do that in a follow up change.

Core: Drop nodeName from AbstractComponent (#34487)
`AbstractComponent` is trouble because its name implies that
*everything* should extend from it. It *is* useful, but maybe too
broadly useful. The things it offers access too, the `Settings` instance
for the entire server and a logger are nice to have around, but not
really needed *everywhere*. The `Settings` instance especially adds a
fair bit of ceremony to testing without any value.

This removes the `nodeName` method from `AbstractComponent` so it is
more clear where we actually need the node name.

With this change, we apply the common test config automatically to all
newly created tasks instead of opting in specifically.

For plugin authors using the plugin externally this means that the
configuration will be applied to their RandomizedTestingTasks as well.

The purpose of the task is to simplify setup and make it easier to
change projects that use the `test` task but actually run integration
tests to use a task called `integTest` for clarity, but also because
we may want to configure and run them differently.
E.x. using different levels of concurrency.

lipsill d5ad3de42e [test] Introduce strict deprecation mode for REST tests (#34338)
#33708 introduced a strict deprecation mode that makes a REST request
fail if there is a warning header in the response returned by
Elasticsearch (usually a deprecation message signaling that a feature
or a field has been deprecated).

This change adds the strict deprecation mode into the REST integration
tests, and makes the tests fail if a deprecated feature is used. Also
any test using a deprecated feature has been modified to pass the build.

The YAML integration tests already analyzed HTTP warnings so they do
not use this mode, keeping their "expected vs actual" behavior.

[ML] Allow asynchronous job deletion (#34058)
This changes the delete job API by adding
the choice to delete a job asynchronously.
The commit adds a `wait_for_completion` parameter
to the delete job request. When set to `false`,
the action returns immediately and the response
contains the task id.

This also changes the handling of subsequent
delete requests for a job that is already being
deleted. It now uses the task framework to check
if the job is being deleted instead of the cluster
state. This is a beneficial for it is going to also
be working once the job configs are moved out of the
cluster state and into an index. Also, force delete
requests that are waiting for the job to be deleted
will not proceed with the deletion if the first task
fails. This will prevent overloading the cluster. Instead,
the failure is communicated better via notifications
so that the user may retry.

Finally, this makes the `deleting` property of the job
visible (also it was renamed from `deleted`). This allows
a client to render a deleting job differently.

Clean up "unused variable" warnings (#31876)
This change cleans up "unused variable" warnings. There are several cases were we 
most likely want to suppress the warnings (especially in the client documentation test
where the snippets contain many unused variables). In a lot of cases the unused
variables can just be deleted though.

[ML] Modify thresholds for normalization triggers (#33663)
[ML] Modify thresholds for normalization triggers

The (arbitrary) threshold factors used to judge if scores have
changed significantly enough to trigger a look-back renormalization have
been changed to values that reduce the frequency of such
renormalizations.

Added a clause to treat changes in scores as a 'big change' if it would
result in a change of severity reported in the UI.

Also altered the clause affecting small scores so that a change should
be considered big if scores have changed by at least 1.5.

[ML] Return both Joda and Java formats from structure finder (#33900)
Previously the timestamp_formats field in the response
from the find_file_structure endpoint contained Joda
timestamp formats.  This change makes that clear by
renaming the field to joda_timestamp_formats, and also
adds a java_timestamp_formats field containing the
equivalent Java time format strings.

[ML] Display integers without .0 in file structure field stats (#33947)
Previously numeric values in the field_stats created by the

decimal point.  This looked unfriendly and unnatural for
fields that clearly store integer values.  This change
converts integer values to type Integer before output in
the file structure field stats.

Add OneStatementPerLineCheck to Checkstyle rules (#33682)
This change adds the OneStatementPerLineCheck to our checkstyle precommit
checks. This rule restricts the number of statements per line to one. The
resoning behind this is that it is very difficult to read multiple statements on
one line. People seem to mostly use it in short lambdas and switch statements in
our code base, but just going through the changes already uncovered some actual
problems in randomization in test code, so I think its worth it.

[ML] Refactor job deletion logic into the transport action (#33891)
The job deletion logic was scattered around a few places:
the transport action, the job manager and the deletion task.
Overloading the task with deletion logic also meant extra
dependencies in the core package which should be unnecessary.

This commit consolidates all this logic into the transport action
and replaces the deletion task with a plain one that needs not be
aware of deletion logic.

Allow TokenFilterFactories to rewrite themselves against their preceding chain (#33702)
We currently special-case SynonymFilterFactory and SynonymGraphFilterFactory, which need to 
know their predecessors in the analysis chain in order to correctly analyze their synonym lists. This
special-casing doesn't work with Referring filter factories, such as the Multiplexer or Conditional
filters. We also have a number of filters (eg the Multiplexer) that will break synonyms when they
appear before them in a chain, because they produce multiple tokens at the same position.

This commit adds two methods to the TokenFilterFactory interface.

* `getChainAwareTokenFilterFactory()` allows a filter factory to rewrite itself against its preceding
  filter chain, or to resolve references to other filters. It replaces `ReferringFilterFactory` and
  `CustomAnalyzerProvider.checkAndApplySynonymFilter`, and by default returns `this`.
* `getSynonymFilter()` defines whether or not a filter should be applied when building a synonym
  list `Analyzer`. By default it returns `true`.

[ML] Allow overrides for some file structure detection decisions (#33630)
This change modifies the file structure detection functionality
such that some of the decisions can be overridden with user
supplied values.

The fields that can be overridden are:

- charset
- format
- has_header_row
- column_names
- delimiter
- quote
- should_trim_fields
- grok_pattern
- timestamp_field
- timestamp_format

If an override makes finding the file structure impossible then
the endpoint will return an exception.

Address license state update/read thread safety (#33396)
This change addresses some issues regarding thread safety around
updates and method calls on the XPackLicenseState object. There exists
a possibility that there could be a concurrent update to the
XPackLicenseState when there is a scheduled check to see if the license
is expired and a cluster state update. In order to address this, the
update method now has a synchronized block where member variables are
updated. Each method that reads these variables is now also
synchronized.

Along with the above change, there was a consistency issue around
security calls to the license state. The majority of security checks
make two calls to the license state, which could result in incorrect
behavior due to the checks being made against different license states.
The majority of this behavior was introduced for 6.3 with the inclusion
of x-pack in the default distribution. In order to resolve the majority
of these cases, the `isSecurityEnabled` method is no longer public and
the logic is also included in individual methods about security such as
`isAuthAllowed`. There were a few cases where this did not remove
multiple calls on the license state, so a new method has been added
which creates a copy of the current license state that will not change.
Callers can use this copy of the license state to make decisions based
on a consistent view of the license state.

[ML] Rename input_fields to column_names in file structure (#33568)
This change tightens up the meaning of the "input_fields" field
in the file structure finder output.  Previously it was permitted
but not calculated for JSON and XML files.  Following this change
the field is called "column_names" and is only permitted for
delimited files.

Additionally the way the column names are set for headerless
delimited files is refactored to encapsulate the way they're
named to one line of the code rather than having the same
logic in two places.

Many files supplied to the upcoming ML data preparation

CSV files are generally not "log" files.  Therefore it
makes sense to rename library that determines the
structure of these files.

Although "file structure" could be considered too broad,
as the library currently only works with a few text
formats, in the future it may be extended to work with
more formats.

Build: Rework shadow plugin configuration (#32409)
This reworks how we configure the `shadow` plugin in the build. The major
change is that we no longer bundle dependencies in the `compile` configuration,
instead we bundle dependencies in the new `bundle` configuration. This feels
more right because it is a little more "opt in" rather than "opt out" and the
name of the `bundle` configuration is a little more obvious.

As an neat side effect of this, the `runtimeElements` configuration used when
one project depends on another now contains exactly the dependencies needed
to run the project so you no longer need to reference projects that use the
shadow plugin like this:

```
testCompile project(path: ':client:rest-high-level', configuration: 'shadow')
```

You can instead use the much more normal:

```
testCompile "org.elasticsearch.client:elasticsearch-rest-high-level-client:${version}"
```

separate change.

The functionality is split into a library so that it can also be
used by a command line tool without requiring the command line
tool to include all server code.

[ML] Removing old per-partition normalization code (#32816)
[ML] Removing old per-partition normalization code

Per-partition normalization is an old, undocumented feature that was
never used by clients. It has been superseded by per-partition maximum
scoring.

To maintain communication compatibility with nodes prior to 6.5 it is
necessary to maintain/cope with the old wire format

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

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.

Tim Vernum 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.

[ML] Move open job failure explanation out of root cause (#31925)
When an ML job cannot be allocated to a node the exception
contained an explanation of why the job couldn't be
allocated to each node in the cluster.  For large clusters
this was not particularly easy to read and made the error
displayed in the UI look very scary.

This commit changes the structure of the error to an outer
ElasticsearchException with a high level message and an
inner IllegalStateException containing the detailed
explanation.  Because the definition of root cause is the
innermost ElasticsearchException the detailed explanation
will not be the root cause (which is what Kibana displays).

HLRest: Move xPackInfo() to xPack().info() (#31905)
Originally I put the X-Pack info object into the top level rest client
object. I did that because we thought we'd like to squash `xpack` from
the name of the X-Pack APIs now that it is part of the default
distribution. We still kind of want to do that, but at least for now we
feel like it is better to keep the high level rest client aligned with
the other language clients like C# and Python. This shifts the X-Pack
info API to align with its json spec file.

HLREST: Add x-pack-info API (#31870)
This is the first x-pack API we're adding to the high level REST client
so there is a lot to talk about here!

= Open source

The *client* for these APIs is open source. We're taking the previously
Elastic licensed files used for the `Request` and `Response` objects and
relicensing them under the Apache 2 license.

The implementation of these features is staying under the Elastic
license. This lines up with how the rest of the Elasticsearch language
clients work.

= Location of the new files

We're moving all of the `Request` and `Response` objects that we're
relicensing to the `x-pack/protocol` directory. We're adding a copy of
the Apache 2 license to the root fo the `x-pack/protocol` directory to
line up with the language in the root `LICENSE.txt` file. All files in
this directory will have the Apache 2 license header as well. We don't
want there to be any confusion. Even though the files are under the
`x-pack` directory, they are Apache 2 licensed.

We chose this particular directory layout because it keeps the X-Pack
stuff together and easier to think about.

= Location of the API in the REST client

We've been following the layout of the rest-api-spec files for other
APIs and we plan to do this for the X-Pack APIs with one exception:
we're dropping the `xpack` from the name of most of the APIs. So
`xpack.graph.explore` will become `graph().explore()` and
`xpack.license.get` will become `license().get()`.

`xpack.info` and `xpack.usage` are special here though because they
don't belong to any proper category. For now I'm just calling
`xpack.info` `xPackInfo()` and intend to call usage `xPackUsage` though
I'm not convinced that this is the final name for them. But it does get
us started.

= Jars, jars everywhere!

This change makes the `xpack:protocol` project a `compile` scoped
dependency of the `x-pack:plugin:core` and `client:rest-high-level`
projects. I intend to keep it a compile scoped dependency of
`x-pack:plugin:core` but I intend to bundle the contents of the protocol
jar into the `client:rest-high-level` jar in a follow up. This change
has grown large enough at this point.

In that followup I'll address javadoc issues as well.

= Breaking-Java

This breaks that transport client by a few classes around. We've
traditionally been ok with doing this to the transport client.

[ML] Don't treat stale FAILED jobs as OPENING in job allocation (#31800)
Job persistent tasks with stale allocation IDs used to always be

However, FAILED jobs are not relocated to other nodes, which leads
to them blocking up the nodes they failed on after node restarts.

node, regardless of whether they are stale or not.

[ML] Fix calendar and filter updates from non-master nodes (#31804)
Job updates or changes to calendars or filters may
result into updating the job process if it has been
running. To preserve the order of updates, process
updates are queued through the UpdateJobProcessNotifier
which is only running on the master node. All actions
performing such updates must run on the master node.

However, the CRUD actions for calendars and filters
are not master node actions. They have been submitting
the updates to the UpdateJobProcessNotifier even though
it might have not been running (given the action was
run on a non-master node). When that happens, the update
never reaches the process.

This commit fixes this problem by ensuring the notifier
runs on all nodes and by ensuring the process update action
gets the resources again before updating the process
(instead of having those resources passed in the request).

This ensures that even if the order of the updates
gets messed up, the latest update will read the latest
state of those resource and the process will get back
in sync.

This leaves us with 2 types of updates:

  1. updates to the job config should happen on the master
  node. This is because we cannot refetch the entire job
  and update it. We need to know the parts that have been changed.

  2. updates to resources the job uses. Those can be handled
  on non-master nodes but they should be re-fetched by the
  update process action.

[ML] Rate limit established model memory updates (#31768)
There is at most one model size stats document per bucket, but
during lookback a job can churn through many buckets very quickly.
This can lead to many cluster state updates if established model
memory needs to be updated for a given model size stats document.

This change rate limits established model memory updates to one
per job per 5 seconds.  This is done by scheduling the updates 5
seconds in the future, but replacing the value to be written if
another model size stats document is received during the waiting
period.  Updating the values in arrears like this means that the
last value received will be the one associated with the job in the
long term, whereas alternative approaches such as not updating the
value if a new value was close to the old value would not.

Remove deprecation warnings to prepare for Gradle 5 (sourceSets.main.output.classesDirs) (#30389)
* Remove deprecation warnings to prepare for Gradle 5

Gradle replaced `project.sourceSets.main.output.classesDir` of type
`File` with `project.sourceSets.main.output.classesDirs` of type
`FileCollection`
(see [SourceSetOutput](https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/java/org/gradle/api/tasks/SourceSetOutput.java))
Build output is now stored on a per language folder.

There are a few places where we use that, here's these and how it's
fixed:

- Randomized Test execution
    - look in all test folders ( pass the multi dir configuration to the
    ant runner )
    - DRY the task configuration by introducing `basedOn` for
      `RandomizedTestingTask` DSL
- Extend the naming convention test to support passing in multiple
  directories
- Fix the standalon test plugin, the dires were not passed trough,
  checked with a debuger and the statement had no affect due to a
  missing `=`.

Only run on Java for build-tools, this is safe because it's a self test.
It needs more work before we could pass in the Groovy classes as well as
these inherit from `GroovyTestCase`

* remove self tests from name check

The self complicates the task setup and disable real checks on
build-tools.
With this change there are no more self tests, and the build-tools tests
adhere to the conventions.
The self test will be replaced by gradle test kit, thus the addition of
the Gradle plugin builder plugin.

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] 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 original settings on full-cluster restart (#30780)

[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.

[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.

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.
