I agree that HttpRequestInfo does not add a ton of value beyond what this class
provides. However, it's the "expected" class to use here. I think it would be
better to use HttpRequestInfo instead of this class. (This will require adding
back the GetKey() method used in the QuicInMemoryServer)

You're right, I think I had seen only HttpRequestHeaders and not HttpRequestInfo
when I made this class. Done.
