Rate Limit interface will be used by KEP, moving this file outside the podresource folder so it can be reused.

I'm fine with generalizing, but I want to point out that this rate-limiting was tailor-made for podresources, so it enshrines some key assumptions and implicit values that can make the aforementioned generalization nontrivial.
IOW, I'm open and supportive for this effort, but I'd expect changes (if nothing else for better UX) needed and perhaps even some kubelet tunables.

I'll review the changeset ASAP.

I have my reservations about reusing this code easily, but I can't see anything wrong with this change, and the new location IMO is a sidegrade wrt the old location.

one last typo please - it's admittedly minor, but the churn to fix later is, out of experience, actually bigger. Other than that LGTM
