Alexander Reelsen bb033f1e00 Watcher: Clear out WatchStore on watch index deletion (elastic/elasticsearch#2807)
If someone deletes the watch index (i.e. by deleting all indices), the watcher
in memory store still contains all the watches and tries to execute watches -
which results in exceptions as the watch itself cannot be updated anymore.

In order to minimize this problem (it cant be get rid of completely), we should
act accordingly if the watch index goes missing (either deleted or closed) and
clear out the memory representation of watches in the watchstore as well as trying
to finish all the current executions.

Closes elastic/elasticsearch#2794
