STORM-2412: Nimbus isLeader check while waiting for max replication
While using local FS blob store, nimbus goes into a state where it
indefinitely waits for max replication (with max replication wait time set to
-1). At this time its also observed that the nimbus that received the topology
submission is no longer the leader.
While waiting for max replication, nimbus can also do the `isLeader` check
and fail the topology submission if its no longer the leader.
Also added some debug logs to better troubleshoot the race conditions when
it happens.
