The native process can only handle one operation at a time, so in order the protect against multiple operation at a time (e.g. post data and flush or multiple post data operations) there should be protection in place to guarantee that at most only a single thread interacts with the native process. The current protection is broken when a job close is executed, more specifically the wait logic is broken here.
This commit changes the threading logic when interacting with the native process by using a custom `ExecutorService` that that uses a single worker thread from `ml_autodetect_process` thread pool to interact with the native process. Requests from the ml apis are initially being queued and this worker thread executes these requests one by one in the order they were specified.
Removed the general `ml` threadpool and replaced its usages with `ml_autodetect_process` or `management` threadpool.
Added a new threadpool just for (re)normalizer, so that these operations are isolated from other operations.

The slack tests seem to fail periodically with not output
This commit tries to add some more verbose output by
making the query more broad and take failures into account
to uncover, what happens in this test.

This change adds a retain field to model snapshots.
A user can set retain to true/false via the update model snapshot API.
Model snapshots with retain set to true will not be deleted by
the daily maintenance service regardless of whether they expired.
This allows users to keep always keep certain snapshots around for
potentially reverting to in the future.

* Removed OPENING and CLOSING job states. Instead when persistent task has been created and
status hasn't been set then this means we haven't yet started, when the executor changes it to STARTED we have.
The coordinating node will monitor cs for a period of time until that happens and then returns or times out.
* Refactored job close api to go to node running job task and close job there.
* Changed unexpected job and datafeed exception messages to not mention the state and instead mention that job/datafeed haven't yet started/stopped.

Add the `.monitoring-alerts-2` index template via the exporter. This
avoids a very common problem where the user wipes out their monitoring
indices manually, which means that the watches would then create an index
with a dynamic mappings.
This adds a mechanism for posting a template that is not associated with a
Resolver (convenient for the forthcoming work _and_ for a future Logstash
index).

The stopped and removeOnCompletion flags are not currently used, this commit removes them for now to simplify things.

Previously a `kill -9` on the `autodetect` process associated with a
job would leave the job in the OPENED state.
Now if the C++ process dies before a request to close the job is made
then the job state is set to FAILED.
For this purpose C++ process death is defined as end-of-file on the
log stream. (Technically it would be possible to get end-of-file on
the log stream while the C++ process was still running, but this
would also represent an unexpected and undesirable situation.)

This to avoid to lose data counts when the job gets restarted on another node.
The job stats api returns live data counts, which may not have been persisted to an index,
so getting the data counts via search api will give us a better guarantee that when
the job gets restarted the datacounts are there too. During job restart a get call is being
done to get data counts in the order to initialize the job.

Previously the GET/PUT/DELETE filters actions were master node actions. This is not necessary since the filters are stored in an index rather than the cluster state. This change makes the actions extend `HandledTransportAction` so they can be run on any node.
The change also makes PutFilterAction.TransportAction use the TransportBulkAction instead of the deprecated TransportIndexAction.

This commit makes the MonitoringDoc immutable and removes the type() and id() methods from "resolvers" so that they are not anymore in charge of computing the documents types and ids. Now each MonitoringDoc knows its type and is able to compute its own id if needed.

This commit marks the x-pack plugin as having a native controller. This
is now a requirement in core for any plugin that forks a native process
to display a warning to the user when they install the plugin.

All of our code supports configuring email addresses in the
email action not only via a JSON array, but also via a comma
separated value (we also have tests for this). However in one bit
we did not support this, where an email template is rendered to
a concrete email.
This commit fixes the last piece, so that users will be able to
specify comma separated email adresses.
The main use case for this is having an array of email addresses,
that can be joined in mustache with a comma in order to send to
several recipients.

This commit ensures that upon reopening a job, the in-memory
model size stats are correctly initialized from the ones
last persisted in the results index.
This fixes the bug that could be seen upon opening a job
that has processed data and immediately calling its _stats
API only to see the model size stats are zero.
In addition, this PR refactors getting the parameters needed to
open an autodetect job:
- Previously, there was a method chaining together multiple
callbacks to the job provider.
- These methods were retrieving data via GETs which is not
going to work with index rollover.
Note, this PR is not eliminating all GETs. More work is needed
to fully support index rollover.

The xcontent parser was only set to read all data to a map
which did not work, when the returned data was in form of an
array (for example the cat API is doing this, if the response
format is set to JSON).

If forced, the internal RemovePersistentTasks API is invoked instead of going through
ML. This will remove the task, which should trigger the task framework to do
necessary cleanup.
At that point, the Delete* APIs interpret a missing task as CLOSED/STOPPED,
so they can be removed regardless of the original state.
