[MARIADB][COMMON] Add support for mariadb-operator

Add template functions for the mariadb-operator resources
and update the mariadb-galera chart to support them
Change the flag to "useOperator" in cassandra to the global setup
and additional labels for cassandra resources
Changed Policy DB users to support the new mariadb User
and fixed db.sh script to wait for the DB user creation
Use the new readiness image 5.0.1 with the "app-name" option
Change the MariaDB-Galera Service to the "primary" to avoid Deadlocks
Fix previous SDNC patch (https://gerrit.onap.org/r/c/oom/+/135308) and
temporary disable MariaDB for SDNR, as it is not compatible to
MariaDB 11
