    Ensure ssh key is active before returning from create_admin_via_nova

    We need to make sure os-collect-config has pulled in the new
    software deployment and committed the changes before returning.

    Also sets the ceph-ansible playbook retries to 3 to make sure we
    don't fail unnecessarily on unpredictable network issues.
