/**
* This limiter will limit requests only after getting a [RetryAfterError] or [ClientRequestException] with
* [HttpStatusCode.TooManyRequests] status code. When block throws [TooMuchRequestsException] or [RetryAfterError],
* in the limiter will be created special [Mutex] for the key, defined in [requestKeyFactory], and this mutex will be
* locked for some time based on type of error. See [limit] for more info
*
* @param defaultTooManyRequestsDelay This parameter will be used in case of getting [ClientRequestException] with
* [HttpStatusCode.TooManyRequests] as a parameter for delay like it would be [TooMuchRequestsException]. The reason of
* it is that in [ClientRequestException] there is no information about required delay between requests
* @param requestKeyFactory This parameter define how to determine request key in limiter
* Simple limiter which will lock any request when TooMuchRequestsExceptions is thrown and rerun request after lock time
