WFA command to set windows service (start, stop, restart)

To make sure iscsi is running fine on a windows machine, i had to check if the service was started.  I've made this command more general.  You can now start, stop or restart a windows service, whether localhost or remote computer.  Credentials are NOT the wfa credentials, but you can get them from the WFA credential store.
