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.
Original commit: elastic/x-pack-elasticsearch@0adb46e658
Cross cluster search uses ClusterSearchShardsAction under the covers.
Without this change, you would need both "read_cross_cluster" and "view_index_metadata" privilegs in order to have permission to execute searches from a remote cluster.
Original commit: elastic/x-pack-elasticsearch@65a6aff329
This commit adds a token based access mechanism that is a subset of the OAuth 2.0 protocol. The
token mechanism takes the same values as a OAuth 2 standard (defined in RFC 6749 and RFC 6750),
but differs in that we use XContent for the body instead of form encoded values. Additionally, this
PR provides a mechanism for expiration of a token; this can be used to implement logout
functionality that prevents the token from being used again.
The actual tokens are encrypted using AES-GCM, which also provides authentication. The key for
encryption is derived from a salt value and a passphrase that is stored on each node in the
secure settings store. By default, the tokens have an expiration time of 20 minutes and is
configurable up to a maximum of one hour.

This change removes the roles from the user in the remote cluster to show that the roles passed
from the source cluster are used in evaluating the user's permissions during multi-cluster search.

We didn't realise it was possible for a qa module to depend on the
test classes of the plugin module, so we duplicated a test class.
But it turns out it IS possible to declare this dependency and avoid
the duplication.

This commit removes the SecuredString class that was previously used throughout the security code
and replaces it with the SecureString class from core that was added as part of the new secure
settings infrastructure.

let close job and stop datafeed apis redirect to elected master node.
This is for cluster state observation purposes, so that a subsequent open and then close job or
start and then stop datafeed see the same local cluster state and sanity validation doesn't fail.

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.

This is analagous of the bwc-zip for elasticsearch. The one caveat is
due to the structure of how ES+xpack must be checked out, we end up with
a third clone of elasticsearch (the second being in :distribution:bwc-zip).
But the rolling upgrade integ test passes with this change.

This commit is response to the renaming of the random ASCII helper
methods in ESTestCase. The name of this method was changed because these
methods only produce random strings generated from [a-zA-Z], not from
all ASCII characters.

This commit adds separate tasks for tribe clusteres which the
cluster formation tasks build their own tasks off. This ensures each
cluster will have its own wait task, so that the tribe node will be able
to wait on the other clusters being up before even trying to start.

Previously force closing a job required extra privileges. Following
the full discussion about what privileges should be required.
Original commit: elastic/x-pack-elasticsearch@4d85314b35
* Removed OPENING and CLOSING job states. Instead when persistent task has been created and
status hasn't been set then this means we haven't yet started, when the executor changes it to STARTED we have.
The coordinating node will monitor cs for a period of time until that happens and then returns or times out.
* Refactored job close api to go to node running job task and close job there.
* Changed unexpected job and datafeed exception messages to not mention the state and instead mention that job/datafeed haven't yet started/stopped.
