NIFI-2419: Ensure that if a node is disconnected that we unregister f…
…or 'cluster coordinator' and 'primary node' roles by updating FlowController to know that it is disconnected. Also removed dead code that was needed in the master-worker clustering paradigm but not for zero-master-clustering

> In my cluster, I see the following Node events for a particular node:
> 07/28/2016 06:17:29 UTC: Acquired role [Cluster Coordinator]
> 07/28/2016 04:53:30 UTC: Node Status changed from CONNECTING to DISCONNECTED due to org.apache.nifi.controller.UninheritableFlowException: Failed to connect node to cluster because local flow is different than cluster flow.
> So the Cluster Coordinator role was obtained even though the node is disconnected. This shouldn't happen.
