Regrouping condition for remote cluster
adding check to check_slave for the case of a demote master in a geo DR setup. Also added check for too many connections in get_slave_info
Added exit code to mysql_demote
Special handling for a remote master switch, no reader_vip loss
Inverted logic for special handling of remote master failover for reader vips
Missed a start_slave after set_master
set_master should start slave, no good reason not to start it
