STORM-2438: added in rebalance changes to support RAS
This is based off #2339 (which is in the first commit). If people want to
review it all together I am fine with closing the other one.
This does a few things
1) It updates the AsyncLocalizer and Slot so that when the jar, conf, or
serialized topology changes the new code is downloaded to a temp location, the
workers are shot, the changes are made, and the workers are brought back up.
2) It adds in changes to the rebalance command so you can adjust config
options and resources in addition to what was there before.
I plan on adding support for generic blobs to optionally cause the workers
to be restarted on update. This would be for things like jars on the classpath.
I plan to do this work in a separate pull request because this is already very
large.
