Remove the dependency of `github.com/gorilla/context`

4

I found `github.com/gorilla/context` had been in maintenance mode, After some search of dependency for it. I truly just find one place that uses the gorilla context, as follows: https://github.com/gin-contrib/sessions/blob/master/sessions.go#L64 ```...

进行hash的时候，传参与定义相反。[具体见](https://github.com/AliwareMQ/amqp-demos/blob/master/amqp-go-utils/utils/UserUtils.go#L43) 这应该是认证模块的bug，已经上线不能更改可以理解，但在sdk里面还是要注明一下吧。我在这个坑里踩了一个半小时。
