#load_new_resource_state ⇒ Object

the new_resource#enabled and #running variables are not user input, but when we do (e.g.) action_enable we want to set new_resource.enabled so that the comparison between desired and current state produces the correct change in reporting. XXX?: the #nil? check below will likely fail if this is a cloned resource or if we just run multiple actions.
