openshift-ansible log

Description of problem:

`openshift-checks/certificate_expiry/easy-mode.yaml` playbook and others from `certificate_expiry` fail when `openshift_is_atomic` is undefined. The error message is:
fatal: [master1.c49d.internal]: 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"}

for all cluster nodes. The error disappears when I set openshift_is_atomic=true in the inventory file.

Version-Release number of the following components:
rpm -q openshift-ansible

How reproducible:

Steps to Reproduce:
1. On the Ansible host (bastion in my case): 
cd /usr/share/ansible/openshift-ansible
2. ansible-playbook playbooks/openshift-checks/certificate_expiry/easy-mode.yaml


Actual results:
Please include the entire output from the last TASK line through the end of output if an error is generated

Error messages (repeated for the number of cluster nodes):
fatal: [master1.c49d.internal]: 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"}

The report is not generated.

Expected results:

Certificate expiry report is generated.
