This change removes the InternalClient and the InternalSecurityClient. These are replaced with
usage of the ThreadContext and a transient value, `action.origin`, to indicate which component the
request came from. The security code has been updated to look for this value and ensure the
request is executed as the proper user. This work comes from elastic/x-pack-elasticsearch#2808 where @s1monw suggested
that we do this.
While working on this, I came across index template registries and rather than updating them to use
the new method, I replaced the ML one with the template upgrade framework so that we could
remove this template registry. The watcher template registry is still needed as the template must be
updated for rolling upgrades to work (see elastic/x-pack-elasticsearch#2950).

Changes to further prepare for feature split with regards to watcher:
- CryptoService has been moved into watcher
- CryptoService.generateKey() has been moved into SystemKeyTools, only
used there
- The creation of the http client/notification classes have been moved
into watcher, no further dependencies on watcher in XPackPlugin
- Each subproject now registers it's own named writeables

In order to prepare for separate source directories, this commit moves
a few packages back into the watcher namespaces. A few of them have been
moved out previously as we thought that it might make sense to have a
dedicated notification API. This wont be the case for watcher on ES
anymore, so we can safely move those back into the watcher space.
Packages affected by this move:
* org.elasticsearch.xpack.common.http
* org.elasticsearch.xpack.common.text
* org.elasticsearch.xpack.common.secret
* org.elasticsearch.xpack.common.stats
* org.elasticsearch.xpack.support
* org.elasticsearch.xpack.notification
Tests have been moved accordingly.
The class `XContentUtils` has been split into one implementation for
watcher and one for security as different methods were used.

The rest test waited for the watch to run in the background, but there
were no guarantees that this really happened. Also it waited for five
seconds, instead of just executing the watch manually.

Some standalone tests set the max script compilation limit. However,
this setting is now set in the main cluster setup in core so it is no
longer needed here. This commit removes these obviated settings in
standalone tests.
Original commit: elastic/x-pack-elasticsearch@089328c8d7
Requests that execute a stored script will no longer be allowed to specify the lang of the script. This information is stored in the cluster state making only an id necessary to execute against. Putting a stored script will still require a lang.
Original commit: elastic/x-pack-elasticsearch@926a7b2d86
The current testing setup only checked if watcher was started, but it
also needs to check for the index template in order to be sure that
everything is set up correctly, before trying to put a watch.

This test failed, because there could have been other results in the
watch history. However by switching to the execute watch API, there
is no need to query the watch history at all. This also removes a 5
second wait time in the test.

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.

Watcher: Use Apache HttpClient for internal Watcher HttpClient
The current implementation based on URLConnection has several drawbacks.
* If server returned HTTP header but then got stuck, no timeout would help, the connection remained stuck
* GET requests with a body were not supported, the method was silently changed to POST
* More complex handling of input/error stream handling, the body could not be read from a single input stream
NOTE: This is a BWC breaker. From now on every part of the URL needs to be encoded properly before it is configured in the requeust builder. This requires an upgrade of all watches.

It used to be that RestTestPlugin "came with" StandaloneTestBasePlugin
but we'd like to use it with BuildPlugin for the high level rest client.
Also fix some license headers.

* Build: Convert xplugins to use new extra projects setup
This change makes the gradle initialization for xplugins look in the
correct location for elasticsearch, which is now as a sibling of an
elasticsearch-extra directory, with x-plugins as a child of the extra
directory.
The elasticsearch side of this change is
elastic/elasticsearchelastic/elasticsearch#21773. This change will enable renaming x-plugins
to x-pack, see elastic/elasticsearch#3643.

In order to prepare to the distributed watch execution, this commit
removes the in memory watch store.
Whenever a watch is needed now, a get request is executed and the parsing
is done. This happens when
* Put
* Get
* Ack
* Activate/Deactivate
* Execute
Note: This also means there are no usage stats currently regarding
the watch count, because we would need to execute a query. This would
require the usage stats to be async, see elastic/elasticsearch#3569
Another advantage is, that there is no dirty flag in the watch itself
needed anymore, because the watch is always the latest. Also write
operations store immediately and dont leave anything in memory.
Also ActionListener.wrap() was used a lot instead of more verbose anonmyous
inner classes.

This commit updates the watch_history.json file so that it includes mappings for the new Jira action. It also update the JiraIssue format so that it now includes the name of the account used to create the Jira issue. It also update the REST tests to check that Jira action result are searchable and hide the user's password.
Original commit: elastic/x-pack-elasticsearch@75888f7748
Refactored ScriptType to clean up some of the variable and method names. Added more documentation. Deprecated the 'in' ParseField in favor of 'stored' to match the indexed scripts being replaced by stored scripts.

This test has been blacklisted and deactivated months ago. This commit reenables this test and moves it at the right place. It also change the test to use the Execute Watch API instead of being sleep based.
