Track responses

• If you wish to include responses in your recoding, run the recording with --input-raw-track-response like this: sudo ./gor --input-raw :8000 --input-raw-track-response --input-raw-realip-header "X-Real-IP" --output-file ./requests_0.gor
• You can use the recored responses to validate that there are no errors during replay by using a GoReplay middleware
