Public bug reported:

With the change of https://review.openstack.org/#/c/465160, 
NUMA related features like CPU pinning, hugepages, and realtime are now
explicitly disabled when using libvirt driver with `virt_type=xen`, 
and compute hosts with libvirt/xen driver are filtered out with NUMATopologyFilter.

We should test and make clear which of the NUMA related features can be supported
by libvirt/xen driver and enable them with documents.

Note: Remenber to update at least these documents when they are enabled.
