Ticket 48957 - Update repl-monitor to handle new status messages
    
    Bug Description:  The replication agreement status messages have changed,
                      and the repl-monitor script was not updated to reflect
                      these changes.  This lead to the html report incorrectly
                      color coding a successfull status.
    
    Fix Description:  Update the script to ignore "Error (0)"
