Description of problem:

The current alias files (/etc/containers/registries.conf.d/000-shortnames.conf, 001-rhel-shortnames.conf,002-rhel-shortnames-overrides.conf) shipped with openshift need to be removed.
These files should be removed from 4.8 RHCOS

These files lead to Crio using the short-name alias feature that will break
current users, pointing the customer image pull to the unexpected image
registry. i.e bug https://bugzilla.redhat.com/show_bug.cgi?id=2021026. According to the discussion[1] these files should be removed since they are unsuitable for Crio.
