Enhancement Request: Support for New Replication Lag Monitoring Variables in MariaDB Monitor

Recent MariaDB Enterprise releases (e.g. 10.6.20-16) introduced new variables for replication lag monitoring:
https://mariadb.com/docs/release-notes/enterprise-server/10.6/10.6.20-16

These variables provide a more stable and consistent way to measure replication lag and address known limitations of the legacy Seconds_Behind_Master metric.

We would like to request support for these new variables in the MariaDB Monitor (MaxScale), allowing them to be used as an alternative source for lag detection and routing decisions.

Example and background on the new approach:
