A Kubernetes admission controller rejects requests that do not pass webhook checks, so it is technically a rate limiter itself.
When deploying to a high-traffic cluster, is there a way to rate limit the requests sent to the admission controller? For example, with rate limiting of 100 requests per second, the admission controller will auto-reject all further requests after the initial 100 requests.

You can try to leverage the EventRateLimit plugin for the admission controller where the controller tried to enforce a limit on the number of event requests that the API Server will accept in a given time slice. Below are some reference docs.
