[libvirt] [PATCH 2/2] Make some vlan, bond, and bridge properties optional in the interface XML.



This is necessary because netcf does not yet know how to get this
information from the kernel, so the live config XML doesn't contain
it, leading to errors when passing it through the current libvirt parsers.
