Configures the {@link ServerBuilder} beyond the defaults of enabling HTTPs and registering a service for
handling enqueued responses. Override this method to configure advanced behavior such as client
authentication and timeouts. Don't call any of the {@code service*} methods, even if you do they will be
ignored as {@link MockWebServerExtension} can only serve responses registered with
{@link MockWebServerExtension#enqueue(HttpResponse)}.
