Alexander Reelsen 79a8f27569 Watcher: Remove WatchLockService (elastic/elasticsearch#4365)
The watch lock service is not really needed, as there is already
a data structure that has information about the currently executing
watches, that can be consulted before executed.

This change will now check, if there is already a watch running with
the current id. If there is not, execution will happen as usual. If
there is however, than a watch record will be created, stating that
the watch is currently being executed - which means that it is either
being executed or in the list of planned executions.

This way users can check in the watch history, if a watch has been executed
more often than it should.

In order to easily search for this, a new execution state called
`NOT_EXECUTED_ALREADY_QUEUED` has been added.

= Elasticsearch X Plugins

A set of Elastic's commercial plugins:

- License
- Security
- Watcher
- Monitoring

= Setup
You must checkout x-plugins and elasticsearch in the same directory as siblings. This
elasticsearch checkout will be used when building x-plugins.

= Build

- Run unit tests:
+
[source, txt]
-----
gradle clean test
-----

- Run all tests:
+
[source, txt]
-----
gradle clean check
-----

- Run integration tests:
+
[source, txt]
-----
gradle clean integTest
-----

- Package X-Pack (wihtout running tests)
+
[source, txt]
-----
gradle clean assemble
-----

- Install X-Pack (wihtout running tests)
+
[source, txt]
-----
gradle clean install
-----

- If you don't work on the UI side of x-plugins, you can force gradle to skip building kibana by adding
  `xpack.kibana.build=false` to your `~/.gradle/gradle.properties`. Alternatively you add `-Pxpack.kibana.build=false`
  on the command line if you only want to do this on individual builds (or `-Pxpack.kibana.build=true` if you need to
  override having added this to your `gradle.properties`).
