Better version of HttpContentCompressor. Netty's HttpContentCompressor fails for chunked writes

The main reason for compressing is that it significantly reduces size of textual api responses (json), which are being used more often than protobuf these days.

Should be revisited with Netty upgrades, to see if this workaround is still needed.
