    Remove the `grafana` volume

    Fixes not being able to add additional plugins at build time due to the
    `grafana` volume being mounted over the existing `/var/lib/grafana`
    directory. This is fixed by copying the dashboards into the container
    from an existing bind mount instead of using the ``grafana`` volume.
    This however leaves behind the volume which should be removed with
    `docker volume rm grafana` or by setting `grafana_remove_old_volume` to
    `True`.
