    NSS: Add InvalidateGroupById handler
    
    There are some situations where, from the backend, the NSS responder
    will have to be notified to invalidate a group.
    
    In order to achieve this in a clean way, let's add the
    InvalidateGroupById handler and make use of it later in this very same
    series.
