Remove MetaDataSerivce and it's semaphores 

MetaDataSerivce tried to protect concurrent index creation/deletion
from resulting in inconsistent indices. This was originally added a
long time ago via #1296 which seems to be caused by several problems
that we fixed already in 2.0 or even in late 1.x version. Indices where
recreated without being deleted and shards where deleted while being used
which is now prevented on several levels. We can safely remove the semaphores
since we are already serializing the events on the cluster state threads.
This commit also fixes some expception handling bugs exposed by the added test
