hi yukon,

I have started implementation. So far i have successfully integrated Apache
Shiro in to current console. APIs for login, logout and current user
details has been created. [1]
<https://github.com/ahmedifhaam/rocketmq-externals/tree/release-rocketmq-console-1.0.0>
Here
you can find my progress. Since this is working successful any current API
or a future API can be easily updated to work with Authentication and
Access control with a single annotation.

I kindly request you to take a look at my proposal and give a feedback if
any changes needed. [2]

Thank you.
