Fix etcd Lock bugs

1. Any connection errors on the first key Set attempt may
   cause 2 clients to think they have acquired the lock if
   the second set attempt succeeds.
2. The wait loop was not checking for 'compareAndDelete'
   events which means that a client may never retry to set
   the lock key.
