Description of problem:

The installation failed due to "stderr: Failed to reset failed state of unit docker.service: Unit docker.service is not loaded." 
The root causes is that the docker service is disabled by default in 1.8.2.  so if we installed docker 1.8.2 and didn't enabled docker service, when we reset-failed docker service after install docker 1.9.1, it will failed. I think we should ignore this failure and continue our job.


Version-Release number of selected component (if applicable):
openshift-ansible/master

How reproducible:
always

Steps to Reproduce:
1. install docker 1.8.2 and don't enable docker service
2. install docker 1.9.1
3. systemctl reset-failed docker.service

Actual results:
