[STORM-233] Removed inline heartbeats to avoid being killed when under
heavy ZK load
I removed the inline heartbeats, although I am happy to switch it over so
that the ZK heartbeat happens first. That should also fix the issue.

> When under a very heavy load ZK can be very slow. If it takes longer than 3
> seconds for a worker to heatbeat in through ZK the first time, this can cause
> the supervisor to time out the worker process and shoot it before it comes up
> fully.
