idrange: only issue warning to restart services for a local range
    
    SIDGEN plugin only uses local ID ranges and thus a restart is really
    needed only when a local range is added, modified or removed.
    
    Also fix the SSSD warning because removal of any range requires restart
    everywhere, not just on a specific server.
