Description of problem:

When the package `yum-utils` is not included in the default or minimal install recommended by the prerequisites and is not covered in the host preparation steps. This leads to the deploy_cluster.yml playbook failing due to the `repoquery` command missing on the nodes.

Version-Release number of the following components:

openshift-ansible-3.9.14-1.git.3.c62bc34.el7.noarch
ansible-2.4.3.0-1.el7ae.noarch
ansible 2.4.3.0
  config file = /home/bbeaudoin/.ansible.cfg
  configured module search path = [u'/home/bbeaudoin/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Feb 20 2018, 09:19:12) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)]

How reproducible:

Deploy the base OS as recommended in the documenation: "RHEL 7.3 or 7.4 with the "Minimal" installation option and the latest packages from the Extras channel, or RHEL Atomic Host 7.4.5 or later." (https://docs.openshift.com/container-platform/3.9/install_config/install/prerequisites.html)

Then, follow the host-preparation steps as documented at https://docs.openshift.com/container-platform/3.9/install_config/install/host_preparation.html

Steps to Reproduce:
1. Deploy the base OS as recommended with the "Minimal" installation option
2. Follow the documented host-preparation steps according to the documentation
3. Start the installation using openshift-ansible/playbooks/deploy_cluster.yml

Actual results:
The installation fails due to /usr/bin/repoquery not being installed.

Expected results:
The `yum-utils` package would have been deployed as a dependency to `openshift-ansible`, or be in the documentation under the host prerequisites, or deployed as part of the installation prior to invocation.

From the module file, the following command was indicated:

    373         '''Base command for repoquery '''
    374         cmds = ['/usr/bin/repoquery', '--plugins', '--quiet']
~~~

The end result is failed unless `yum-utils` is installed and present on the machines.
