Add a way to send a 204 no body?

[rbygrave]

I don't think we have a nice/good way to send a 204 response without a body via Context interface?

It would be context.write(new byte[0]) ... write an empty byte array. Do we need a better option like content.sendEmpty(204)? With Nima/Helidon its res.status(NO_CONTENT_204).send();

handled by #78, if you don't write any response a 204 with no body is sent automatically.

Hmm ok. Will go with that. Pondering if I like the explicit approach like helidon ... will ponder that some more.

I mean anything we add will be nothing but a placebo

Yeah, just pondering that sometimes its nice when things are explicit ... in the avaje-http generated code for Nima ... when a controller method returns null we explicitly generate code to send a 204 no body response - part of me like that in that its nice and explicit.
