STORM-3117 prevent deleting blobs while topologies still active
Prevented crashing nimbus if blob is deleted during a getClusterInfo call.
However, once nimbus is restarted, if there was an active topology with a
missing blob, nimbus will be stuck validatingAcls and not be able to schedule.
To get around this, I prevented deleting blobs unless a topology is not
active. As a bonus, this should also fix race conditions we have seen between
the scheduling loop and a kill topology occurring with the cleanup thread
deleting the blobs.
