Subject: Generate SDNR notification even on timeout

If a request to SDNR times out, the actor class does not generate a
notification for the DCAE_CL_RSP topic.  Rather than modifying the
actor, decided to modify models to handle that case.  Seems like that's
where it belongs anyway, as notifications are more of an application-
level behavior.
