title: Vert.x httpClient/webClient process response chunk by chunk or as stream
body: <p>I have application with vert.x and asyncHttpClient. I want to replace asyncHttpClient with vert.x httpClient (webClient), but i need to have ability to process response by chunks or by small parts of data (like org.asynchttpclient.AsyncHandler in AsyncHttpClient) or like a stream. Is it possible? I look at custom BodyCodec, but i can`t understand data flow in custom WriteStream.</p>
