user: create crud
The API should provide a functionality to create and modify users.
Modifications: Modify repository for PagingAndSorting Extend the controller by common CRUD methods and use the existing implementations of the interface. Use the cerebrum error handling for the user.
Result: Now it's possible to create, read (single or multiple (+PagingAndSorting)), update and delete users via REST API calls.
