[MARIADB][SO] Connect MariaDB Galera via master node

To avoid "lock" situations all clients of the mariadb-galera
cluster should use the "primary" service, which connects
to the master node.
This service is provided by the mariadb-operator.
Additionally for SO the bugfix for "local" DB configuration
is fixed.
Additionally missing readiness checks added to so-cnfm-lcm and
so-etsi-nfvo-ns-lcm to wait for the DB job to complete
