    grafana: add bootstrap during upgrade

    Upgrading from Victoria to Wallaby with Monasca enabled fails waiting
    for Grafana to start.

    Grafana defaults to enabled if Monasca is enabled in Wallaby (was
    default disabled in Victoria), so the database user and tables don't
    necessarily exist prior to the upgrade.

    Running `kolla-ansible upgrade` then attempts to start the Grafana
    container, but fails to include the bootstrap task (which creates the
    db) so the container is unable to start with a database connection
    error, from the grafana container logs:

      service init failed: failed to check table existence: Error 1045:
      Access denied for user 'grafana'@'xxx' (using password: YES)

    This change performs a bootstrap of Grafana during upgrade. It is
    required only for the Wallaby release where the default change is
    introduced.
