we can now do numa testing in the gate so we can also add tempest testing this cycle.
artom has recently gotten whitebox to run (more work to do https://review.opendev.org/#/c/691062/)
and i do want to get my multi numa nfv testing job https://review.opendev.org/#/c/679656/ at least
in experimental and perodic pipelines. i would like it to be in check eventually but baby steps.

i dont think these should be a blocker for any of this work but i think we shoudl take advantage
of them to contiue to improve the numa testing in gate.
