> We should handle the error more gracefully and informatively. Currently if user did the following:
> gfsh> start locator --name=locator
>  gfsh> shutdown --include-lcoator=true
>  gfsh> start locator --name=locator --load-cluster-configuration-from-dir=true
> the console message says "Cluster configuration service has been started, but its not running yet",
>  and there is an NPE in the log:
>  [error 2017/07/18 10:22:38.357 PDT locator <Pooled Message Processor 1> tid=0x41] null
>  java.lang.NullPointerException

> The error message if no directory is specified, should be saying:
> {code:java}
> The option load-cluster-configuration-from-dir=true is specified but the option -cluster-config-dir needs to be set with a directory to the cluster config file.{code}
> The error message if the directory is specified but cluster config file is not found in that directory:
> {code:java}
> No cluster configuration is found in <specified directory>{code}
