NUMA, huge pages & cpu pinning are all general purpose Nova features. While
NFV / Telcos will be a large user of them, they're not the only. As such
these features should be tested in a general Nova test suite, as we would
for any other Nova functionality, not in a telco-specific test suite as
that just re-inforces the impression that this is a niche feature only
useful for a few use cases.
