Open Stack

Thanks Gema!

So it's my understanding (which is limited at best) that zuul
currently doesn't support something like "this job has to run on
nodepool X", which would be necessary. We might need to add some sort
of metadata for nodepools and be able to specify in zuul job that
"this job has to land on node with metadata X", like architecture:
arm64.
