jbossdm-standalone-restarter plugin

* Trigger a stop and a start steps when deploying on a JBoss Standalone server. (`restartRequired`, `restartRequiredOnNoop`)
* Define a stop and a start control task on the `jbossdm.Standalone` CI.
[minor] "JBoss CLI"? And "...end with `.py` the commands are executed using the JBoss CLI. Otherwise, the commands are executed on the command line."

Could you explain what you mean by the "can be used..." bit?
