--------------------------------------------------------------

[~junrao] It was due to some quota sensor exception on the broker side. The 
broker also has some issue that it did not give back the error response in 
correct format. I haven't got a chance to dig into that yet. I will create 
another ticket for that after the investigation.

> In the NetworkClient, we remove the in flight request before we successfully 
> parse the response. If the response parse failed, the request will not be 
> fulfilled but just lost. For a producer request, that means the callback of 
> the messages won't be fired forever.
> We should only remove the in flight request after response parsing succeeds.
