No major update. All is porting.

I will update the version_client.txt in a later PR.

I think these two record json could be removed due to they don't playback

@ChenTanyi
I would still put it in.

1. Playback fails due to certificate files. If we can somehow circumvent it (though not very likely) we can directly use that json for playback.
2. Even it does not playback, it might still provide information on server response that might help when later we try to find server behavior changed or not.
