  - 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.

  - Improve common secret template

    Improve common secret template by adding:
    - ability to generate secrets if they are not provided
    - ability to fail the deployment if marked secret is not provided
    - support for using already existing secret instead of creating
      a new one
