Background
After creating a message instance, you must create an application user so that the application can send and consume messages on this message instance.
l Application user: A RocketMQ client requires permission verification when connected to the server for production and consumption. A RocketMQ client user is called an application user. Apart from password verification, a topic can be specified for the user. This means that the user can only produce and consume the messages of the specified topic rather than other topics.
