MDBF-829 - Update MariaDB Server cnf

Separate configs for PROD and DEV. Updated docker-compose to choose the right one based on environment.
TODO: maybe a templating engine in the future to de-deduplicate configuration settings.

Took all the configuration settings from current PROD MariaDB Server installation.
