    Adds support for deploying infrastructure VMs on the seed hypervisor.
    These can be used to provide supplementary services that do not run well
    within a containerised environment or are dependencies of the control
    plane.  See `story 2008741
    <https://storyboard.openstack.org/#!/story/2008741>`__ for details.
