MariaDB clustercheck script has not been maintained and it will not work with MariaDB 11.4 (the next LTS version). This is because clustercheck.sh uses ``mysql*`` commands but from MariaDB 11.4, those commands are not supported. The health check of MariaDB server containers will be done by new script which comes with change [1]. Without MariaDB clustercheck, MariaDB server becomes only container image in the family, so mariadb-base and mariadb-server dockerfiles are merged. To avoid breaking changes, the name 'mariadb-server' is retained. Follow-up to rename references in Kolla and K-A from 'mariadb-server' to 'mariadb' would be nice.
