Restore the previous state on Controller Service restart

Currently, when stopping and starting a controller service to make any changes, all of its dependent controller services and processors are also stopped.  In some situations, we have some of the dependent controller services & processors stopped for a variety of reasons, so don't want/need those to be restarted when the parent is restarted.

Consider adding a "Restore service and referencing components" to the "Scope" options, which would restore the previous state of the parent controller service's referencing components.  That would require storing the state of those when the parent is stopped, then restoring it when it's started again.  If the regular "Service and referencing components" scope is selected, then previous state should be purged.
