Return more detailed response from controllers

[petak5]

Controllers should return tuple containing a dictionary which will be converted to JSON by the view and a return code.
Error message will be sent in the dictionary.

Examples:
return {'status': 'success', 'data': user}, 200
return {'status': 'failed', 'msg': 'User not found'}, 404

• User Controller
• • user-methods
• • links
• • feedback
• Project Controller
• • project-methods
• • links
• • feedback
    -[ ] Authentication
    -> Login/register should not return errorcodes, but return a "status" property in the query and immediately redirect to the specified redirect url. the rest is up to frontend.

After trying a few things I have opted to return 3 things from teh controller methods.
A data object (e.g User) that implements a .as_dict() method, a msg and a returncode
in most views this will be wrapped using the wrap_response() method from the utils module.
This might then look like this in code wrap_response(*userController.update_user(get_jwt_identity(), **request.get_json()))
But other methods, that work with the returned data can still do so.
This is the best compromise I could find @petak5
