Provide an e2e skip helper checking for available resource

@janetkuo @dims this is the promised util function, but unfortunately I just learned that dynamic client suffers from the problem I've fixed in the manually written one (https://github.com/kubernetes/kubernetes/pull/29187) I need to look into the dynamic client in that case :/

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).

resource type has not been specified as an argument to kubectl get
