@tillrohrmann I've reworked the client response parsing: the
`ClientHandler` now only parses the response as JSON, whereas the conversion to
the respective `ResponseBody` is handled in a future declared in
`RestClientHandler#submitRequest()`. With this the `ClientHandler` is once
again immutable and we don't have to do any casts.
I've also reworked how handlers communicate failures: The `HandlerResponse`
classes have been removed, and handlers may now throw a (checked)
`RestHandlerException` or complete the future with an exception (with special
treating for RestHandlerExceptions). Unchecked or non-RestHandlerExceptions are
still treated as implementation errors and will return a "500 Internal Server
Error".
