Enable per-user feature permission control for by admins

### Feature Summary

Let admins control the permissions of using some features for users. One motivation is: for feature described in #3935, only trusted users should have the capability of using the feature.

### Proposed Solution or Design

- **Store the permission info in the database**: Add a column in `user` table called `permission`. This field is a json type and can store the permission the user has.
- **Introduce the frontend dashboard for admins**: Add a new column in admin user dashboard. Admins can toggle the per-user permission via the dashboard
