installation log with inventory file embedded

Description of problem:
In 93a2fcd9 commit, we have such code is merged:
- name: Wait for all control plane pods to become ready
  oc_obj:
    state: list
    kind: pod
    name: "master-{{ item }}-{{ openshift.node.nodename | lower }}"
    namespace: kube-system
 <--snip-->
  retries: 60
  delay: 5
  with_items:
  - "{{ 'etcd' if inventory_hostname in groups['oo_etcd_to_config'] else omit }}"
  - api
  - controllers

when etcd is not co-located with master, the "omit" would return some invalid value, which lead to the installation failure.

Version-Release number of the following components:
openshift-ansible-3.10.0-0.58.0.git.0.d8f6377.el7.noarch

How reproducible:
Always

Steps to Reproduce:
1. define etcd group and master group, they are not co-located together.
2. trigger installation
3.

Actual results:
TASK [openshift_control_plane : Wait for all control plane pods to become ready] ***
