NettyConnector - HOST header contains port & 307 works with buffered post

[jansupol]

Host header contains port for non 80 & 443 ports
Status 307 with post and buffered entity does not hang

jerseyRequest.setStreamProvider(new OutboundMessageContext.StreamProvider() {
@OverRide
public OutputStream getOutputStream(int contentLength) throws IOException {
replaceHeaders(jerseyRequest, nettyRequest.headers()); // WriterInterceptor changes
if (!nettyRequest.headers().contains(HttpHeaderNames.HOST)) {
nettyRequest.headers().add(HttpHeaderNames.HOST, jerseyRequest.getUri().getHost());
}
headersSet.countDown();

                    return entityWriter.getOutputStream();
                }
            });

port needs to be added here as well.
