* Zookeeper connection timeout is now configurable (via storm.zookeeper.connection.timeout config)

* Storm is now less aggressive about halting process when there are Zookeeper errors, preferring to wait until client calls return exceptions.

* Can configure Zookeeper authentication for Storm's Zookeeper clients via "storm.zookeeper.auth.scheme" and "storm.zookeeper.auth.payload" configs

* Bug fix: Realize task ids when worker heartbeats to supervisor. Some users were hitting deserialization problems here in very rare cases (thanks herberteuler)
