Add ppc architecture for NUMA

[Sudipta Biswas]

Post this commit: https://review.openstack.org/#/c/170780/11/nova/virt/libvirt/driver.py,

the NUMA topology reporting depends on the host architecture.

The current check includes arch.I686, arch.X86_64 only.

This bug is filed to include the ppc64/ppc64le architectures included to the list, since they use the same libvirt driver for KVM based systems.

https://review.openstack.org/#/c/245765/ - I don't know why the review was not updated with the bug.
This patchset has been posted out a few months back - and all review comments have been incorporated. I am just waiting for some cores to take a look at the same for a merge. Assigning it back and putting it in progress.

    libvirt: Add ppc to supported arch for NUMA

    This patch includes the ppc64/ppc64le architectures to the list
    of host architectures that support NUMA via the libvirt driver.

    This change is for the PowerPC based servers that use the libvirt
    driver. This also introduces the minimum libvirt version needed
    for PowerPC to support NUMA from Nova.

    Also note, that in order to retain the unit test that excluded
    PPC from the NUMA supported architectures, an arbitrary choice
    of architecture is made (S390) - that is not a part of the list
    that supports NUMA.
