Add easy way to set Read/WriteTimeout instead of http://targetliu.com/golang-iriszhong-tong-guo-pluginshe-zhi-httpchao-shi-shi-jian/

Instead of this article, I just found, shows you how to inject the main

iris.ListenTo(config.Server{WriteTimeout: 5* time.Second, ReadTimeout=
5*time.Second, ListeningAddr:":8080"})

config/server.go
