MXS-1266: Master GTID registration: MASTER_USE_GTID=Slave_pos

Browse Source 
MASTER_USE_GTID=Slave_pos is now handled by CHANGE MASTER TO

If mariadb10_master_gtid is On

MASTER_LOG_FILE is no longer required, only MASTER_USE_GTID=Slave_pos

Slave_pos must be set before to empty value or request value:

set @@global.gtid_slave_pos = '0-10116-194';
