This commit changes the MonitoringIt and XPackRestIT tests so that the
disableMonitoring() method now use the XPack Usage API in order to check
that the monitoring exporters are correctly disabled. It checks at the
beginning of the tests (all exporters must be disabled before running
the test) and also at the end of the test.
This commit also fixes a bug in MonitoringIT where the Bulk thread pool
active queue was wrongly extracted from the response's map, forcing the
test to always wait for 30sec.

Provides more verbose messaging around errors and possible causes when the tool aborts.
This change is primarily focused on errors connecting to the Elasticsearch node when TLS is enabled on the HTTP connection.
Original commit: elastic/x-pack-elasticsearch@aa8f7c6143
When certgen configuration was read from an input file (`-in` option) validation errors were collected but never reported. Depending on the type of error this may have caused the tool to exit with an internal error (e.g. NPE).
Validation is now applied after parsing the file and if errors are found the tool exits.

Adds the GET overall_buckets API.
The REST end point is: GET
/_xpack/ml/anomaly_detectors/job_id/results/overall_buckets
The API returns overall bucket results. An overall bucket
is a summarized bucket result over multiple jobs.
It has the `bucket_span` of the longest job's `bucket_span`.
It also has an `overall_score` that is the `top_n` average of the
max anomaly scores per job.

The execution state is kind of a global indicator if a watch has been
running successfully and is used by the watcher UI.
However this field is only stored in the watch history but not part of
the watch status, thus it is not available everywhere. In order to
simplify the watcher UI this commit also adds the field to the
watch status which is stored together with the watch.
It is stored under the `status.execution_state` field as `status.state`
is already taken. This is also reflects with the name of the java class.
The WatchStatus class does not contain serialization checks, as this is
intended to be backported to 6.x, where those checks will be added.
Once the backport is done, the old execution state field can be fully
deleted from the master branch in another commit (syncing with Kibana
folks required).

Do not execute bind on on the LDAP reader thread
Each LDAP connection has a single associated thread, executing the handlers for async requests; this is managed by the LDAP library. The bind operation is blocking for the connection. It is a deadlock to call bind, if on the LDAP reader thread for the same connection, because waiting for the bind response blocks the thread processing responses (for this connection).
This will execute the bind operation (and the subsequent runnable) on a thread pool after checking for the conflict above.

When getting a single bucket, the get_buckets API can take a timestamp
either in the body or in the URL. Prior to this change, if a timestamp
was specified in the URL but a body not containing a timestamp was specified
(either empty or containing other parameters like exclude_interim or sort)
then it would cause a bad_request exception. This in turn causes problems
for clients that cannot send a body when GETting and always send a body when
POSTing.
This change fixes get_buckets to always read any timestamp in the URL, even
when a body is sent.

weakened by the decision to grant many "minimal" privileges to all users

I noticed this while working on a previous issue with atomic move writer
(silent swallowing of exceptions). Namely, atomic move writer has
dangerous semantics. The problem is as follows: atomic move writer works
by writing lines to a temporary file, and then in its close method it
replaces the target path with the temporary file. However, the close
method is invoked whether or not all writes to the temporary file
succeeded (because writers obtained from atomic move writer are used in
try-with-resources blocks, as they should be). There is no way to
distinguish that the writer is being closed in a successful scenario
versus a failure scenario. In the close method for atomic move writer,
the target file is replaced by the temporary file. This means that the
target file is replaced whether or not writing to the temporary file
actually succeeded. Since these atomic move writers are used for user
configuration files (users and user_roles), a failure here can lead to
data loss for the user, a tragedy!
There is another (less serious) problem with the atomic move
writer. Since the close method tries to move the temporary file in place
of the existing file, the temporary file can be left behind if there is
another failure in the close method (e.g., closing the underlying file
after writing, or setting the permissions on the temporary file). This
means that in some situations, atomic move writer will leave temporary
files behind (which is not definitively not atomic).
This commit replaces the atomic move writer with a safer mechanism. We
still perform the write atomically in the following sense: we write to a
temporary file. Either writing to that file succeeds or it fails. If
writing succeeds, we replace the existing file with the temporary
file. If writing fails, we clean up the temporary file and the existing
file remains in place.

Original commit: elastic/x-pack-elasticsearch@3a52bad460
When a watch is executed currently, it gets passed an in-memory
watch object, that was loaded, before the execution started.
This means there is a window of time, where an old watch could still
be executing, then a watch gets loaded for execution, then the old watch
execution finishes and updates the watch status and thus reindexes the
watch.
Now the watch, that got loaded for execution, executes and tries to
store its watch status, but fails, because the version of the watch
has changed.
This commit changes the point in time where the watch is loaded. Now
this only happens, while a watch is in its protected execution block,
and thus we can be sure, that there is no other execution of the watch
happening.
This will primarily impact watches, that execute often, but their
runtime is longer than the configured interval between executions.
Side fix: Removed some duplicate testing method and moved into
WatcherTestUtils, fixed a tests with a ton of if's with random booleans
into separate tests.

Today we require a pre-shared key to use the token service. Beside the
additional setup step it doesn't allow for key-rotation which is a major downside.
This change adds a TokenService private ClusterState.Custom that is used to distribute
the keys used to encrypt tokens. It also has the infrastructur to add automatic key
rotation which is not in use yet but included here to illustrate how it can work down
the road.
This is considered a prototype and requires additioanl integration testing. Yet, it's fully
BWC with a rolling / full cluster restart from a previous version (also from 5.6 to 6.x)
since if the password is set it will just use it instead of generating a new one.
Once we implement the automatic key rotation via the clusterstate we need to ensure that we are
fully upgraded before we do that.
Also note that the ClusterState.Custom is fully transient and will never be serialized to disk.
