http trace

HTTP Request trace, timing and requset's informations. Timing include dns, connect, tls, first reponse byte and so on.

trace, ht := NewClientTrace()
ctx := context.Background()
ctx = httptrace.WithClientTrace(ctx, trace)
req, _ := http.NewRequest("GET", "https://www.baidu.com/", nil)

req.WithContext(ctx)
resp, _ := http.DefaultClient.Do(req)

ht.Finish()
stats := ht.Stats()
fmt.Println(stats)
fmt.Println(resp.Status)
