service, ...).

Specific configuration:
  * name of the db to create if needed

NBI chart
---------

Ability to start a mariadb container, with a chart consistent with other
common charts (readiness, liveness, persistence, resources, nfs,
service, ...).

Specific configuration:
  * name of the db to create if needed
  * name of the user that has access to the db
  * password of the user that has access to the db
