dummy suite fails in OpenStack
When the dummy suite was first added, it included a commit https://github.com/ceph/ceph-qa-suite/pull/664/commits/a016f29e211e378a50fd833d940abbb49449c37b that runs only the user playbook, instead of the entire ceph-cm-ansible.
When running the dummy suite in OpenStack, the user playbook alone is not enough for the test to succeed. Therefore, the above commit was reverted by https://github.com/ceph/ceph-qa-suite/commit/d0280d791054604cff41244681dc76810af5db79
However, some time later the commit was reintroduced by https://github.com/ceph/ceph-qa-suite/pull/908
