Patch is attached that will restart the Falcon server on source cluster, if service like HDFS is down/unreachable on remote cluster. [~venkatnrangan] Please review.

> Falcon fail to restart, if any service in the cluster entity is not reachable or down.
> For example, if there are clusters X, Y, Z. In cluster X, submit cluster entities which points to services of cluster Y & Z. Execute some replication jobs from cluster X to Y and even to cluster Z as well. If after certain duration, cluster Z HDFS service is down due to maintenance activity and at the same time we require to restart Falcon service on cluster X due to some reason, then Falcon will fail to restart on cluster X. 
> This issue has been reported internally at Hortonworks.
