This PR updates the ratelimit logic to work with the newly introduced changes to serviced_query and the logic that sends a query to the network. It also introduces ratelimit-backoff and ip-ratelimit-backoff for an optional more aggressive countermeasure when the limit is reached.
@wcawijngaards: this changes the function signature for send_query. I don't remember if for that change I have to also address something else than what is already addressed here.
