Adds following validations:
- aggregations must contain date_histogram or histogram at the top level
- a date_histogram has to have its time_zone to UTC (or unset which
defaults to UTC)
- a date_histogram supports calendar intervals only up to 1 week
to avoid the length variability of longer intervals
- aggregation interval must be greater than zero
- aggregation interval must be less than or equal to the bucket_span

If jobs are being deleted then the operations required to get stats
could fail with unexpected exceptions. When stats for multiple jobs
were being requested, this would previously cause the whole operation
to fail.
This commit changes the stats endpoint to ignore jobs that are being
deleted.

When this happens it means the job has been deleted, which in turn means
the C++ process has been stopped, so there's no need to send it a message
and hence no problem worth logging a stack trace for.
This differs from elastic/x-pack-elasticsearch#896 because elastic/x-pack-elasticsearch#896 was for a similar situation with
closed jobs, whereas this one is for deleted jobs.

The test is too rigid on checking the right number of node_stats documented that are collected. It happens if a node takes time to start, the node_stats count % numNodes will always be different than 0.
It also adds more logging for LocalBulk failures.

In order to prevent tasks state updates by stale executors, this commit adds a check for correct allocation id during status update operation.

This commit changes the LocalExporterTests so that it now test
various randomized cases in a single test. This should speed up
the test as well as minimize the failures due to multiple start
/stop of the exporter. It also uses the MonitoringBulk API
instead of calling the Exporter instances, which makes more sense
since it is the normal way to index monitoring documents.

This commit adds separate tasks for tribe clusteres which the
cluster formation tasks build their own tasks off. This ensures each
cluster will have its own wait task, so that the tribe node will be able
to wait on the other clusters being up before even trying to start.

Detector configs are validated both by our C++ and by our Java code.
If the C++ is stricter than the Java then error reporting is poor.
This commit adds two extra validation checks to the Java code that
were already present in the C++ validation.

It's possible for a C++ process to exit between the time when a
config update message for it is queued and the time that message
is processed. This commit ensures we don't spam the log with a
stack trace in this situation, as it's not a problem at all.

Original commit: elastic/x-pack-elasticsearch@81af8eaf70
Aggregated data extraction is done in 2 phases:
1. search
2. process response
The first phase cannot be currently cancelled. However, it usually
is the fastest of the two.
The second phase processes the histogram buckets in the search
response into flat JSON and then posts the result stream to the job.
This phase can be split into batches where a few buckets are posted
to the job at a time. Cancelling can then work between batches.
This commit changes the AggregationDataExtractor to process the
search response in batches. The definition of a batch is crucial
as it has to be short enough to allow for responsive cancelling,
yet long enough to minimise overhead due to multiple calls to the
post data action. The number of key-value pairs written by the
processor is a good candidate for a batch size measure. By testing,
1000 seems to be an effective number.

Original commit: elastic/x-pack-elasticsearch@ce3a172411
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.

Previously force closing a job required extra privileges. Following
the full discussion about what privileges should be required.
Original commit: elastic/x-pack-elasticsearch@4d85314b35
* 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).
