Change rbac roleref to reflect the information we want
@liggitt @ericchiang This is a version of https://github.com/kubernetes/kubernetes/pull/31359 which updates the `RoleRef` to be (I think) the type that we want, with a group, resource, and name.
This is **not** backwards compatible with any existing data. I'm ok with doing this since rbac was considered alpha, but its something to consider.
If we want this instead, I'll close the previous pull (or update it with this content).
