Fix CS replication management.
    
    The master side should be on the local side, replica1, not the
    remote. This required reversing a few master variables. This impacts
    the naming of the replication agreements.
    
    When deleting an agreement pass in the DN of that agreement
    rather than trying to calculate what it is on-the-fly. We cannot
    be sure which side is the master/clone and since we search for it
    anyway to determine if the agreement exists it is more correct
    to use what we find.
    
    The force flag wasn't being passed into del_link so there was no way
    to force a deletion.
