* 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.
