    Work around bad libvirt-python wheel

    The following package must always build from source:

    - libvirt-python:
      A pre-built wheel can be missing libvirt capabilities
      from the installed version of libvirt-bin, leading to
      nova-compute failing to start.

    Note that this is a re-implementation of
    https://review.openstack.org/388027

    The re-implementation is necessary as there are no
    group_vars scoped to the repo servers. If these vars
    are added to group_vars/all then the compute nodes
    would also install from source every time, whereas
    it only needs to be done in the repo server's wheel
    build process.
