Description of problem:
If docker-1.13 is present on the repository, OpenShift health-check would check a higher docker version than requested and fail immediately. This is not reasonable because the higher docker version that installer checks may not what the user will use or install. 

We already have atomic-openshift-docker-excluder that prevents from installing incorrect docker version, instead the OpenShift health check should check if the supported docker version is available on current repository.

Version-Release number of the following components:
openshift-ansible-3.7.36-1.git.0.0f4a93c.el7.noarch.rpm

How reproducible:
always

Steps to Reproduce:
1. Trigger rpm installation on RHEL that have docker-1.12, docker-1.13 repo configured.


Actual results:
Failure summary:


  1. Hosts:    qe-ghuang-master-etcd-xxx.qe.rhcloud.com, qe-ghuang-node-registry-router-xx.qe.rhcloud.com
     Play:     OpenShift Health Checks
     Task:     Run health checks (install) - EL
     Message:  One or more checks failed
     Details:  check "package_version":
               Some required package(s) are available at a version
               that is higher than requested
                 docker-1.13.1
               This will prevent installing the version you requested.
               Please check your enabled repositories or adjust openshift_release.


Expected results:
If docker-1.12 is what we're going to support in 3.7, we just need to check if docker-1.12 is available on the host regardless of docker-1.13 or others.
