Pulling an unauthenticated image from Red Hat registry returns terms acceptance error

Issue

• When importing an image from registry.access.redhat.com, it tells me to accept the Red Hat subscription agreement.

• When using oc import-image it fails with an internal error:

  $ oc import-image rhscl/redis-5-rhel7 --from=registry.access.redhat.com/rhscl/redis-5-rhel7 --confirm
  error: tag latest failed: Internal error occurred: registry.access.redhat.com/rhscl/redis-5-rhel7:latest: unsupported: This repo requires terms acceptance and is only available on registry.redhat.io
