    Low: libcrmservice: don't consider a cancelled recurring operation as failed
    
    This takes care of an recurring (pun intended) and annoying regression test
    issue when cancelling LSB monitors.
    
    If an instance of the recurring operation was *not* in-flight at the time,
    services_action_cancel() would set the operation status to cancelled and leave
    the rc alone (which would be 0).
    
    If an instance *was* in-flight, the instance would be killed, and the child
    exit handler would set the status to error and the rc to PCMK_OCF_SIGNAL
    (which would get mapped to PCMK_OCF_UNKNOWN_ERROR for client notification).
    The result would cause the regression test ignore the notification and get a
    timeout instead.
    
    Now, the exit handler also sets status cancelled and rc 0 in this situation.
    
    This should benefit actual cluster usage in the same situation, though those
    effects have not been extensively traced. The behavioral difference would be in
    process_lrm_event(). Most likely it avoids spurious monitor failures.
