This makes the use more futureproof as it guards against any cleanup the `withResolver` function might want to do after a resolver is used. This means the whole federator needs to run inside `withResolver`, but I cannot really see any downsides to this.

General question: can we move https://github.com/wearezeta/documentation/blob/master/topics/federation/federation-design.md to wire-server/docs now? Or to wire-docs? The documentation repo is deprecated by confluence anyway.
More review chunks coming up!

LocalCall -> Request RemoteCall -> FederatedRequest RouteToRemote -> Outward RouteToLocal and RouteToInternal -> Inward Function names have also been adjusted in many places. We still have modules externalServer internalServer and 'Remote' in federator. Perhaps we should also rename the 'remote' module?
