Use common secret template in mariadb-galera

Instead of defining the secret in some custom way let's use the common
template (common.secret). To avoid some issues in ONAP components that
depend on this chart let's do not remove for now the default username
and password. We will do this when all services properly utylize
secrets to store mariadb credentials.
