Added some sample Java filters that do nothign but route to api.test.netflix.com.

Not working yet, though.

When I do a response.close(true), I see headers get flushed to my final HttpResponse.

I also see the following warning:
Aug 12, 2014 9:40:01 PM io.netty.channel.ChannelOutboundBuffer safeSuccess
