Add end-to-end test that serve can handle canceled requests

This test actually tests the serve process brought in by
the ["end-to-end", "with serve"] rule. It starts several requests to
serve and, while serve is still building those, stops the clients.
The serve service should handle those aborted requests gracefully
and afterwards still be ready to take on a new requests.
