some background task doing something with yum behind the installer's back maybe?

Seems to affect yum in general: https://bugzilla.redhat.com/show_bug.cgi?id=1479533 . The problem is spurious and looks like retrying the operation will help.

[jupierce]

Adding @sdodson since openshift-ansible will need to perform the retry.

Dupe of #14772 and we've removed epel so this particular issue should never happen again but we're still prone to external failures and we're working to add retries to all of the yum tasks as they're prone to failure due to external systems.
