Storing the request-response

Each request to server and response from 3rd party sevice is logged in a in-memory database:

// To save
db := DB()
db.Save(id, reqDump, respDump)

// To check current rows of db
for k, v := range db.Rows() {
	fmt.Println("For id", k)
	fmt.Println("Request", string(v.Request))
	fmt.Println("Request", string(v.Response))
}
