libvirt: Support VM creation with vpmems and vpmems cleanup
Add the vpmems config into guest config xml according to
resources info in the instance object, then users can build
a VM with vpmems. Also this patch add the support for
data cleanup on the backend device of the vpmems.
note:
We modify the root <domain> element generated for libvirt to
include <maxMemory> elements when memory device is used.[1]
Requiring vpmems implies a NUMA topology because libvirt won't let us
use vpmem without NUMA.[2]
