[Openstack] neutron, nova and vif_plugging_* in nova.conf

Hi,
The flag makes the libvirt driver use the instance event mechanism to
wait for neutron to confirm that the VIF plugging is complete before
actually starting the VM. In order for this to work correctly you also
Need to make sure that Neutron is aware of these event.
Thanks
Gary
