    Use the running MariaDB server image for backups

    If the container image used by Mariabackup is different than the
    one used by MariaDB server, it's possible that mariabackup and mariadb
    are incompatible. This may cause backup operations to fail.

    This change queries the running MariaDB server container's image and
    uses it when taking a backup. If MariaDB server isn't running on the
    host it falls back to the image defined in configuration.

    The separate mariabackup_image, mariabackup_tag and
    mariabackup_image_full variables are no longer required and have been
    removed.
