[Enhancement] Check rate limit & reset limit for request

[JE4GLE]

I have the following use case:

I have an endpoint receiving API POST requests, which require an API key for authentication. I want to rate limit only wrong API keys.

1. Request is received
2. Rate limit is checked, without being increased
3. If rate is not exceeded, the API key is checked
   • If the key is correct, the limit for this specific request (IP/UA) is reset
   • Is the key incorrect, the rate limit value is increased

I haven't been able to find the following two functionalities:

• Check, if the rate limit is already exceeded without increasing the value
  limiter.isLimitExceeded(event);
• Reset the limit for a specific request
  limiter.reset(event);

What do you think? Do you agree that this will be a fine addition to the collection of functions this rate limiter has?
