BUG#47016: rpl_do_grant fails on PB-2 with a failing connect        The test case rpl_do_grant fails sporadically on PB2 with "Access denied for user 'create_rout_db'@'localhost' ...". Inspecting the test case, one may find that if issues a GRANT on the master connection and immediately after it creates two new connections (one to the master and one to the slave) using the credentials set with the GRANT.        Unfortunately, there is no synchronization between master and slave after the grant and before the connections are established. This can result in slave not having executed the GRANT by the time the connection is attempted.        This patch fixes this by deploying a sync_slave_with_master between the grant and the connections attempt.
