A conflict exception signifies the job state is not opened, thus
we are better off stopping the datafeed.

Changes the logging of LDAP authentication failures from "always" to "only if the user failed to be authenticated"
Previously there were cases (such has having 2 AD realms) where successful user authentication would still cause an INFO message to be written to the log for every request.
Now that message is suppressed, but a WARN message is added _if-and-only-if_ the user cannot be authenticated by any realm.
This is implemented via a new value stored in the ThreadContext that the AuthenticationService choses to log (or not log) depending on the result of the authenticate process.

The PR detects if SMILE is being provided, then correctly slices the stream such that each document is parsed individually. This is required because jackson's SMILE parser is stricter than it's JSON parser and will stop parsing when it hits a streamSeparator (unlike JSON, which will eagerly try to find more objects to parse).

The change applies chunking by default on aggregated datafeeds.
The chunking is set to a manual mode with time_span being
1000 histogram buckets.
The motivation for the change is two-fold:
1. It helps to avoid memory pressure/blowing.
Users may perform a lookback on a very long period of time. In that
case, we may hold a search response for all that time which could
include too many buckets. By chunking, we avoid that situation
as we know we'll only keep results for 1000 buckets at a time.
2. It makes cancellation more responsive.
In elastic/x-pack-elasticsearch#862 we made the processing of a search response cancellable in a
responsive manner. However, the search phase cannot be cancelled at
the moment. Chunking makes the search phase shorter, which will
result to a better user experience when they stop an aggregated
datafeed.
Also note the change sets the default chunking_config on datafeed
creation so the setting is no longer hidden.

When a datafeed task is created but it cannot be assigned the task
has a null status. This means _stats report it as stopped, however
deleting it fails. In addition, it's a better experience to error
the start datafeed request all together and give the user the chance
to fix his data indices.
This change fails a datafeed-start if it cannot be assigned.

Increase the timeout to give enough time for a datafeed to

This is the second step to avoid hitting the default timeout.
The first was ensuring aggregated datafeed is cancellable in

the duration of the search, which will make cancellation even

There was a problem with the way CompositeBytesReference was used in the
StateProcessor. In the case of a large state document we ended up with a
deeply nested CompositeBytesReference that then caused a deep stack and N^2
processing in the bulk action processor.
This change uses an intermediate list of byte arrays that get combined into
a single CompositeBytesReference to avoid the deep nesting.
Additionally, errors in state processing now bubble up to close the state
stream, which will cause the C++ process to stop trying to persist more state.
Finally, the results processor also times out after a similar period (30 minutes)
to that used by the state processor.

It has been observed that Amazon EBS volumes created from snapshots can
have very high latency the first time a given block is accessed. This
can lead to named pipes taking longer than 2 seconds to create.
Since the native processes create their named pipes immediately after
startup, and this only takes a fraction of a second on a local disk, 2
seconds was considered a generous timeout, but it seems that in the case
of a remote NAS with lazy provisioning it's not long enough. During
debugging a latency of just over 3 seconds was observed. The timeouts
have been increased to 10 seconds.

Before this change, aggregation datafeeds used the histogram bucket
key as the record timestamp that is posted to the job. That meant
that the latest_record_timestamp at the end of a datafeed run was
the start of the latest seen histogram bucket. Upon continuing the
datafeed, the search starts from one millisecond after the
latest_record_timestamp. Hence, data may be fetched for a second time.
This change requires a max aggregation on the time_field nested in
the histogram bucket. It then reads the timestamp from that agg.
This ensures datafeed can restart without duplicating data.

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.

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.

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.)

Submit job updates to a concurrent queue when job update has been processed by ClusterService. Then from a background thread delegate the job updates to the node running the autodetect process. This maintains the same order as how the job config updates have occurred to the cluster state and thus preventing job config updates to the same job to arrive in the wrong order to the job's autodetect process. (the expectation is that in practise this will rarely happen)
The behaviour of the update api changes with this pr, because the api now returns when the update has been made to cluster state, whereas before it would return when the update was made to the autodetect process too. Updating the autodetect process happens in the background. I think that this change in behaviour is acceptable.
