    Make sure we start nova-compute after ironic-conductor.
    
    We need to ensure that ironic-conductor starts before nova-compute.
    This is to workaround an issue where nova-compute tries and fails to
    call plug_vifs, this in turn report a vm_state error which, in this
    case is a false positive.  See lp#1777608 for more.
    
    We ensure ordering by forcing puppet to restart nova-compute after
    ironic-conductor in the case of undercloud upgrade/update.

  It boils down to a ordering issue between openstack-ironic-conductor
  and openstack-nova-compute, a simple reproducer is:

  sudo systemctl stop openstack-ironic-conductor
  sudo systemctl restart openstack-nova-compute

  on the undercloud.
