This introduces the `hyper::service` module, which replaces `tokio-service`. Since the trait is specific to hyper, its associated types have been adjusted. It didn't make sense to need to define `Service<Request=http::Request>`, since we already know the context is HTTP. Instead, the request and response bodies are associated types now, and slightly stricter bounds have been placed on `Error`. The helpers `service_fn` and `service_fn_ok` should be sufficient for now to ease creating `Service`s. The `NewService` trait now allows service creation to also be asynchronous. These traits are similar to `tower` in nature, and possibly will be replaced completely by it in the future. For now, hyper defining its own allows the traits to have better context, and prevents breaking changes in `tower` from affecting hyper. Closes #1461 BREAKING CHANGE: The `Service` trait has changed: it has some changed associated types, and `call` is now bound to `&mut self`. The `NewService` trait has changed: it has some changed associated types, and `new_service` now returns a `Future`. `Client` no longer implements `Service` for now. `hyper::server::conn::Serve` now returns `Connecting` instead of `Connection`s, since `new_service` can now return a `Future`. The `Connecting` is a future wrapping the new service future, returning a `Connection` afterwards. In many cases, `Future::flatten` can be used.
