I made a few changes to thing. I fixed the race condition and I addressed
the review comments, but I also put in some optimizations to storm submitter.
We were literally calling getClusterInfo 3+ times for each topology submission,
and because the ultimate goal of STORM-2190 is to make it more scalable this
helps a lot. There is still some lock contention, but it is much better then
it was before.
If things look good here I will backport the changes to my other pull
request.
