        Run `neutron-sanity-check` on the controller nodes to find out
        potential issues with Neutron's configuration.

        The tool expects all the configuration files that are passed
        to the Neutron services.

      groups:
        - post-deployment

    # The list of Neutron configuration files and directories that
    # will be passed to the Neutron services. The order is important
    # here: the values in later files take precedence.
    configs:
