Description of problem:
When running the openshift_certificate_expiry playbook after updating to v3.11.43, the playbook fails with the below errors on all hosts:

~~~
TASK [openshift_certificate_expiry : Ensure python dateutil library is present] ****************************************************
task path: /usr/share/ansible/openshift-ansible/roles/openshift_certificate_expiry/tasks/main.yml:2
fatal: [hostc]: FAILED! => {
    "msg": "The conditional check 'not openshift_is_atomic | bool' failed. The error was: error while evaluating conditional (not openshift_is_atomic | bool): 'openshift_is_atomic' is undefined\n\nThe error appears to have been in '/usr/share/ansible/openshift-ansible/roles/openshift_certificate_expiry/tasks/main.yml': line 2, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n---\n- name: Ensure python dateutil library is present\n  ^ here\n"
}
