Ticket 47655 - Improve replication total update logging
    
    Description:  If an online initialization failed, the error message was vague and
                  did not fully imply that it failed.
    
                  Also, in repl5_tot_waitfor_async_results() we did not take into
                  account if progress was being made, and our timeout was incorrectly
                  set to 5 minutes, instead of 30 seconds.
