Deal with port commonly when hypervisor is XenServer
When neutron is deployed with hypervisor is XenServer, current
implementation will grab port's iface-id via xapi, but this isn't
the proper way:
Port's iface-id is already set when creating VM or hot plugging
VIFs in nova project, so there is no need to grab it via xapi

Title:
XenAPI: With ovs polling mode, Neutron gets the error of
oslo_rootwrap.wrapper.FilterMatchNotExecutable
Status in neutron:
Fix Released
Bug description:
When enabled polling mode for XenAPI, the neutron q-domua always get
the error of oslo_rootwrap.wrapper.FilterMatchNotExecutable. See the
following log.
With ovs polling mode, ovs will report data to neutron once any ovs DB
update. So there is chance to report partialy data for vifs before ovs
DB synced-up with xapi. so it will invoke xe command to get iface-id.
But xe is not in the allowed command list. So it will raise errors.
