If a persistent task throws an exception, the persistent tasks framework will no longer try to restart the task. This is a temporary measure to prevent threshing the cluster with endless restart attempt. We will revisit this in the future version to make the restart process more robust. Please note, however, that if node executing the task goes down, the task will still be restarted on another node.

* [ML] Removes direct dependency on Jackson Parser
The classes that read data from the post data action ready to write to the autodetect process had a direct dependency on Jackson’s `Parser` class. This changes makes those classes depend on XContent instead making them consistent with the way we parse requests and data across Elasticsearch and X-Pack.
* Simplify json record reader
This commit removes the unnecessary `AbstractJsonRecordReader` and `JsonRecordReader` interfaces/classes. These are not required as we do and should only have one implementation of reading json records.

Removes the transport layer dependency from PersistentActions, makes PersistentActionRegistry immutable and rename actions into tasks in class and variable names.
Original commit: elastic/x-pack-elasticsearch@e3e5b79c28
The action name is currently inconsistent with the class name.
Also as more types of jobs will be added, they should reuse the existing actions,
so it make more sense to gave a generic job name for the action name. Note that
it is ok to have additional rest handlers for new type of jobs.

The LdapRealm submits runnables to the generic thread pool when a bind is necessary as a bind must
be a synchronous operation and we do not want to block network threads on this. However, the
generic threadpool could be full and this runnable could get queued. When this happens requests
appear to hang; to prevent this we submit a delayed executable that will stop the runnable from
attempting to connect to Ldap and provide an exceptional response to the listener.

This commit fixes the merging of field level security rules from multiple roles. Prior to 5.2, the
merging was treated as the merging of languages whereas after 5.2, this incorrectly became a merge
of all rules meaning a single wildcard could cause denials to be ignored.
Original commit: elastic/x-pack-elasticsearch@42f9e6d8b0
This commit removes the blocking invocation of bulk requests in monitoring as in some cases this
can lead to exhaustion of the generic threadpool, which effectively prevents the node from
operating normally.
One behavior change that is made by this commit is the MonitoringService will no longer wait
indefinitely when closing as this can lead to a node blocking forever and never shutting down.
Instead a wait of 10 seconds is added, which aligns with the security index audit trail's behavior
on shutdown.

Datafeed state was always stopped when the stats

This commit fixes the issue by expanding _all into

The wait condition used for integ tests by default calls the cluster
health api with wait_for_nodes nd wait_for_status. However, xpack
overrides the wait condition to add auth, but most of these conditions
still looked at the root ES url, which means the tests are susceptible
to race conditions with the check and node startup. This change modifies
the url for the authenticated wait condtion to check the health api,
with the appropriate wait_for_nodes and wait_for_status.

This moves the index structure to using a single, shared index
(.ml-anomalies-shared). Custom indices can still be used by manually
setting `results_index`.
An alias is always created which points from `.ml-anomalies-<jobid>`
to `.ml-anomalies-shared`.
User defined indices are prepended with "custom-"
Index helper functions have been renamed to make this clear. Furthermore,
accessing an index should always be done either by fetching the
currently configured index/alias from the state, or using the preconfigured
alias. Because the user can specify a custom physical index, it is
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

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.

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.
