[CI] nested virtualization support in OpenStack CI

I like Sean's idea. Can we create jobs based on nested KVM & customized OS?
If CI is stable enough, we can move non-voting to voting.

Well, having these jobs non-voting means you aren't relying on them to protect you from merging changes which might break nested virtualization or fail to work with it. But that aside, to even have a guarantee it would be available at all we'd need a separate node label for all our images which is restricted to providers where we can expect it. For example, I've heard that doing nested virt acceleration for KVM guests in our Xen-based providers is a long way from being possible.
