New rate limiting solution is currently not applied to EPP poll, login and logout + any REPP requests. Rate limiting must be extended to all EPP and REPP requests. It might be good idea to exclude logout though so registrars are always able to end their sessions. Instead error rate limiting could be used here instead to stop spamming of logout requests i.e. too many erroneous requests per minute or second
