EmptyDir volumes are expected to be disabled in Online (potentially for a short
period of time so this patch will likely get reverted someday).
EmptyDir volumes are something a user can explicitly add to their PodSpecs, and
in some cases new-app will automatically do it for them. As such we need to
clarify firstly that this volume type is disabled in Online, how the error will
surface (which can vary depending on if the user is creating a template/DC/RC
vs a pod itself), and how to work around the problem.
This PR depends on the following origin PR: openshift/origin#6659
And is somewhat related to the SCC Docs PR for AllowEmptyDirVolumePlugin: #1528
