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).

This change makes 2 improvements to the max_running_jobs setting:
1. Namespaces it by adding the xpack.ml. prefix
2. Renames "running" to "open", because the "running" terminology
is not used elsewhere
The old max_running_jobs setting is used as a fallback if the new
xpack.ml.max_open_jobs setting is not specified. max_running_jobs
is deprecated and (to ease backporting in the short term) will be
removed from 7.0 in a different PR closer to release of 7.0.

The deprecated handlers should have been removed earlier, but are now
going to to away finally.
Also the watcher restart action has been removed, mainly because users
should not blindly restart, but always make sure, that watcher is
stopped correctly before restarting. This had been removed from the
transport action previously.

This is step 2 of elastic/x-pack-elasticsearch#1604
This change stores `model_memory_limit` as a string with `mb` unit.
I considered using the `toString` method of `ByteSizeValue` but it
can lead to accuracy loss. Adding the fixed `mb` unit maintains
the accuracy, while making clear what unit the value is in.

This is related to elastic/x-pack-elasticsearch#1217. This PR removes the default password of
"changeme" from the reserved users.
This PR adds special behavior for authenticating the reserved users. No
ReservedRealm user can be authenticated until its password is set. The
one exception to this is the elastic user. The elastic user can be
authenticated with an empty password if the action is a rest request
originating from localhost. In this scenario where an elastic user is
authenticated with a default password, it will have metadata indicating
that it is in setup mode. An elastic user in setup mode is only
authorized to execute a change password request.

This changes the validation criteria we use for user and role
names in the file realm, native realm, and the
realm-agnostic code in x-pack security. The new criteria is:
A valid username's length must be at least 1 and no more than 1024
characters. It may not contain leading or trailing whitespace. All
characters in the name must be be alphanumeric (`a-z`, `A-Z`, `0-9`),
printable punctuation or symbols in the https://en.wikipedia.org/wiki/Basic_Latin_(Unicode_block)[Basic Latin (ASCII) block],
or the space character.

Prior to this change, if the persistent tasks framework noticed that a
job was running on a node that was isolated but has rejoined the cluster
then it would close that job. This was not ideal, because then the job
would persist state from the autodetect process that was isolated. This
commit changes the behaviour to kill the autodetect process associated
with such a job, so that it does not interfere with the autodetect process
that is running on the node where the persistent tasks framework thinks it
should be running.
In order to achieve this a change has also been made to the behaviour of
force-close. Previously this would result in the autodetect process being
gracefully shut down asynchronously to the force-close request. However,
the mechanism by which this happened was the same as the mechanism for
cancelling tasks that end up running on more than one node due to nodes
becoming isolated from the cluster. Therefore, force-close now also kills
the autodetect process rather than gracefully stopping it. The documentation
has been changed to reflect this. It should not be a problem as force-close
is supposed to be a last resort for when normal close fails.

This commit adds a new Logstash component to x-pack to support the config management work. Currently, the functionality in this component is really simple; all it does is upload a new index template for `.logstash` index. This index stores the actual LS configuration.
On this template is bootstrapped in ES, Kibana can write user-created LS configs which adhere to the mapping defined here. In the future, we're looking into adding more functionality on the ES side to handle config documents, but for now, this is simple.

When a user or client intend to delete a datafeed
and its job, there is benefit into ensuring the
datafeed has gracefully stopped (ie no data loss).
In constrast, the desired behaviour is to stop and
delete the datafeed as quickly as possible.
This change adds a force option to the delete
datafeed action. When the delete is forced,
the datafeed is isolated, its task removed and,
finally, the datafeed itself is removed from the
metadata.

Detectors now have a field called detector_index. This is also now the
field that needs to be supplied when updating a detector. (Previously
it was simply index, which was confusing.)
When detectors are added to an analysis_config it will reassign
ascending detector_index values starting from 0. The intention is
never to allow deletion of detectors from an analysis_config, but
possibly to allow disabling them in the future. This ensures that
detector_index values in results will always tie up with detector_ids
in the detectors that created them.

As fields with underscores will be disallowed in master, and we have to
prepare the upgrade, this commit renames the _status field to status.
When the 5.x upgrade logic is in place in the 5.x we can remove all the
old style _status handling from the master branch.
Note: All the BWC compatibility tests, that load 5.x indices are now
faking a finished upgrade by adding the `status` field to the mapping
of the watches index.

The distribution of watches now happens on the node which holds the
watches index, instead of on the master node. This requires several
changes to the current implementation.
1. Running on shards and replicas
In order to run watches on the nodes with the watches index on its
primaries and replicas. To ensure that watches do not run twice, there is
a logic which checks the local shards, runs a murmurhash on the id and
runs modulo against the number of shards and replicas, this is the way to
find out, if a watch should run local. Reloading happens
2. Several master node actions moved to a HandledTransportAction, as they
are basically just aliases for indexing actions, among them the
put/delete/get watch actions, the acknowledgement action, the de/activate
actions
3. Stats action moved to a broadcast node action, because we potentially
have to query every node to get watcher statistics
4. Starting/Stopping watcher now is a master node action, which updates
the cluster state and then listeners acts on those. Because of this watches
can be running on two systems, if you those have different cluster state
versions, until the new watcher state is propagated
5. Watcher is started on all nodes now. With the exception of the ticker
schedule engine most classes do not need a lot of resources while running.
However they have to run, because of the execute watch API, which can hit
any node - it does not make sense to find the right shard for this watch
and only then execute (as this also has to work with a watch, that has not
been stored before)
6. By using a indexing operation listener, each storing of a watch now
parses the watch first and only stores on successful parsing
7. Execute watch API now uses the watcher threadpool for execution
8. Getting the number of watches for the stats now simply queries the
different execution engines, how many watches are scheduled, so this is
not doing a search anymore
There will be follow up commits on this one, mainly to ensure BWC compatibility.
