CLOUDSTACK-6000: When expunging fails, move volume state back to

> I think there's a hole in the volume lifecycle.  I've been noticing
> volumes lingering that should have been cleaned up, and it seems to be
> a bug in the state machine for the volumes:
>             s_fsm.addTransition(Destroy, Event.ExpungingRequested, Expunging);
>             s_fsm.addTransition(Expunging, Event.ExpungingRequested, Expunging);
>             s_fsm.addTransition(Expunging, Event.OperationSucceeded, Expunged);
>             s_fsm.addTransition(Expunging, Event.OperationFailed, Expunging);
> If a volume is in Destroy state, it goes to Expunging when the delete
> operation is requested. If the delete fails, it remains in expunging.
> The storage garbage collector will never try to clean up that volume
> again, since it only lists volumes in 'Destroy' and attempts those.
> You can only get to Expunging from Destroy, it makes sense to change
> that last line to revert the volume state back to Destroy if the
> expunge operation failed, so that it will try again next time.
