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.

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.)

The job stats api returns live data counts, which may not have been persisted to an index,

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.

removed the custom rescheduling and cancelling.

impossible to determine the physical index "by convention" now.
The helpers have been configured to reflect that.

This commit adds the ability for x-pack extensions to optionally
provide custom roles providers, which are used to resolve any roles
into role descriptors that are not found in the reserved or native
realms. This feature enables the ability to define and provide roles
from other sources, without having to pre-define such roles in the security
config files.

As part of authentication, we use a iterating action listener to perform asynchronous authentication against the realm
chain. When this listener is called with a response or a failure, it could be called from a thread that is not owned by
the Elasticsearch threadpool such as a LDAPConnectionReader thread. When this happens, we need to ensure that the
ThreadContext is not left with items in it otherwise we leave behind things like Authentication and hit obscure errors.
This commit stores the context when the listener calls the consumer or onResponse/onFailure is invoked, which prevents
us from polluting a external thread's ThreadContext.

Some json builders in the codebase were not closed. even
though this is not needed for the BytesStreamOutput being used,
there is more closing logic in the jackson classes, which we

close.

When the datafeed indexes are concrete indexes, the search
will throw IndexNotFoundException, thus a notification is being
generated. However, when the indexes are patterns, the search
does not fail.
This commit adds a warning when a lookback-only datafeed
retrieves no data as it is certain that the user misconfigured
something and it's useful to make him aware of it.

If any format other than json is sent, it should get converted to json, as watcher works under the assumption that the script is a template, hence json.

On Windows the JVM hangs during shutdown if the native controller process
is still running. A thread dump suggests this is because of a finalizer being
blocked. We can avoid the problem by explicitly telling the controller to exit
when the node is stopped. Although the hang is Windows-specific, it doesn't
hurt to do this on *nix too.

Refactors xcontent serialization of Request and Status to use their writable names instead of action name. That simplifies the parsing logic, allows reuse of the same status object for multiple actions and is consistent with how named objects in xcontent are used.

The DnRoleMapper was changed when moving to asynchronous authentication, which introduced a regression that leads to a
NPE being thrown on file refresh. The cause is the addition of a null listener from the LdapRealm upon construction.
This change removes the listener constructor argument as it was always null or a empty runnable and adds a check in the
addListener method to ensure the listener is not null. Finally, the DnRoleMapperTests had a bug where the temporary
filenames did not have the correct suffix and tests were not actually testing what was intended.

Currently, both the NativeUsersStore and NativeRolesStore can undergo
multiple state transitions. This is done primarily to check if the
security index is usable before it proceeds. However, such checks are
only needed for the tests, because if the security index is unavailable
when it is needed, the downstream actions invoked by the
NativeUsersStore and NativeRolesStore will throw the appropriate
exceptions notifying of that condition. In addition, both the
NativeUsersStore and NativeRolesStore had much duplicate code that
listened for cluster state changes and made the exact same state
transitions.
This commit removes the complicated state transitions in both classes
and enables both classes to use the SecurityTemplateService to monitor
all of the security index lifecycle changes they need to be aware of.
This commit also moves the logic for determining if the security index
needs template and/or mapping updates to the SecurityLifecycleService,
and makes the NativeRealmMigrator solely responsible for applying the
updates.

This PR introduces a service component that is scheduled to run
once per day, around 30 minutes past midnight, local time.
Listeners can be subscribed to the service in order to get notified
when the next service trigger occurs so that they can execute
management tasks.
Currently, there are 2 such listeners: one is performing removal
of results and the other of model snapshots that have expired
their retention period.
Finally, note that the service is only installed on the master
node to ensure there is only one running on the cluster.

A job allocation is either a job task in OPENING state or a job task that has been assigned to an executor node, but the executor node hasn't had the opportunity to set the job task status to OPENING.
In order to keep track of restarted tasks, `allocationIdOnLastStatusUpdate` field was added to `PersistentTaskInProgress` class.
This will allow persistent task implementors to detect whether the executor node has changed or has been unset since the last status update has occured.

This commit ensures that the authentication sets the correct version on the stream when it is serialized over the wire
so that there is not a version mismatch between the authentication and the connection it came from.
Original commit: elastic/x-pack-elasticsearch@267d7068f4
Any failure to communicate with an LDAP server should be treated as if authentication failed rather than a fatal "stop the world" error.
Because the AD realm validates the user's password by attempting to bind to the directory with that username/password combination, connection failures are to be expected and must be handled gracefully because the AD realm may not be the last realm in the order-chain, and any exception would prevent later realms from being tested.

This change adds checks to the following machine learning actions to check that machine learning is permitted by the license before executing the request and throw and exception if the license forbids it:
* Create job
* Create data feed
* Open job
* Start data feed
This is not a final list of the restrictions we want to have in place if the license forbids ML access but it serves as a starting point and can be easily updated following further discussions.
The change also moves the `transportClientMode` check to `createComponents` so we don’t try to start the server parts of machine learning (job manager, connection to named pipes etc.) if we are running in a transport client.
