> Currently Script based action handler does nothing if instances are not present.
> For Example I tried to start-hbase service before launching a cluster then it terminates without error message leaving the user unaware of what happened
> bin/whirr start-services --config hbase-ec2.properties 
> Starting to run scripts on cluster for phase start on instances: 
> Finished running start phase scripts on all cluster instances
> It should throw an error like " No Cluster instances were detected. Please use launch-cluster to launch the cluster"
