[COMMON] Apply changes for mariadb-init project

Two changes are intended with this commit:
- (for proper name mapping) Update VolumeMounts names to be:
(mariadb-init for mountPath /db-init/)
(mariadb-conf for mountPath /db-conf/)
originally it was reversed.
- Make use of (common.mariadbService) and (common.mariadbPort) defined
in (common/templates/_mariadb.tpl) into job.yaml. This will reflect the
proper values for mariadb service name and port in case of local
installation.
