Return Context from xray.Handler about aws-xray-sdk-go

@skatsuta , thank you for reaching out to us. I read your issue and the current xray.hander method can solve your problem without returning a Context. Here I provide an example.

    http.Handle("/", xray.Handler(xray.NewFixedSegmentNamer("example"), http.HandlerFunc(func(w http.ResponseWriter, r *http.Request)  {
            w.Write([]byte("Hello!"))
            xray.Capture(r.Context(), "d", func(ctx context.Context) error {
            sess := session.Must(session.NewSession())
            svc := s3.New(sess)
            xray.AWS(svc.Client)
            input := &s3.ListObjectsInput{
                Bucket:  aws.String("xray-daemon"),
            }
            _, _ = svc.ListObjectsWithContext(ctx, input)
            return nil
        })
    })))
    http.ListenAndServe(":8000", nil)

As the example above indicates, you can create a new subsegment inside the request segment in the wrapped handler by calling r.Context since it returns a Context. Let me know whether it works for your implementation or not.
