Allow defining CRDs from a single version

Part of istio#3127. Goes with a
corresponding tools change; this will fail until that merges.

This just shows DR. The tool will support both the new and old way (we
can remove the old way if we want), so we don't have to move everything
at once. We will, though. I kept it to one so its easy to review first.
