    Mount openshift-ansible working dir with 'z' option

    On RHEL8, deployment fails with a bunch of permission issue while the
    openshift-ansible container image tries to read files from /var/lib/mistral/openshift/openshift/inventory/.

    We need to add 'z' option while mounting the
    /var/lib/mistral/openshift volume.
