`RequestId` is a monotonically increasing integer, starting at `1`. A `RequestId` is unique for a single `RequestResponse` behaviour, but not across multiple `RequestResponse` behaviours. Thus when handling `RequestId` in the context of multiple `RequestResponse` behaviours, one needs to couple the protocol name with the `RequestId` to get a unique request identifier. This commit ensures that pending requests (`pending_requests`) and pending responses (`pending_response_arrival_time`) are tracked both by their protocol name and `RequestId`.
