Require way to do OpenShift and Docker Hub testing without publishing public images on RHCC or Docker Hub

 Started by discussion on CBD-3279. We already create Red Hat-based images for every Operator build. However we are being told that it is impossible to do any testing in OpenShift without publishing the images onto the Red Hat Container Catalog (RHCC). Not only is this a potentially significant waste of time for us (RHCC is a pain in the neck to deal with), but it means that we are constantly releasing our internal and untested content onto the open internet where anyone can download it.

I cannot believe that OpenShift has no concept of "testing images".  If they do, then we need to start using it. If they do not, then we need to use our contacts inside Red Hat and inform them we cannot support their environment until they do.
