Notes for Reviewer

The changelog will only be updated once the feature is ready.

This MR implements the Server part for the Request/Response communication and add the unit tests.

I'm not that happy with the raw pointer in the API but it is modeled after the PublisherPort/SubscriberPort. Ideally, only references would be used, but I'm not sure if this should be done in this PR or if all the ports should be adjusted. Currently this is only internal API so we could change this later without our users suffering on breaking API calls.
