Title: Revised test setup to reuse domain if available

Built a fork ami with this change and it passed: https://ci.dev.openshift.redhat.com/jenkins/job/fork_ami/260/

That's not going to be as conclusive as doing a lot of concurrent builds but I think we'll need to merge this to see about those scenarios.
