MaxScale failover fails with MASTER_SSL=1 default in MariaDB 11.4

Starting from MariaDB 11.4, SSL is enabled on the server by default. This change also means that when a CHANGE MASTER command is executed, the option MASTER_SSL=1 is automatically applied by default.

During a MaxScale switchover or failover, the CHANGE MASTER command is issued to redirect replication to the new master. However, even if replication_master_ssl=0 is configured in MaxScale and ssl is disabled at the server level, the generated CHANGE MASTER command still includes MASTER_SSL=1 as its default.

MaxScale should honor replication_master_ssl=0 and override the default MASTER_SSL=1 setting introduced in MariaDB 11.4 when generating the CHANGE MASTER command.
