Hi. This pull request adds the ability to forward the client's real IP address to the gRPC backend.

gRPC backend can get the real IP address of the client using a similar snippet:

func UserIP(ctx context.Context) string {
	md, ok := metadata.FromIncomingContext(ctx)
	if ok {
		if xRealIP := md.Get("x-real-ip"); len(xRealIP) > 0 {
			return strings.Split(xRealIP[0], ",")[0]
		}
	}
	p, ok := peer.FromContext(ctx)
	if ok {
		return p.Addr.String()
	}
	return ""
}
