This commit splits the Browbeat CI out by workload by passing in
different playbooks, mostly just makes a different playbook for yoda
because why deploy an overcloud before testing yoda? makes no sense and
adds another couple of hours to the test. We also add an integration test
playbook but that doesn't seriously diverge from the normal testing playbook
at the moment
