Fix #1075

Logic flow:

• Read entries in model.list
• Get information about model_id and path/to/model.yml
• Read yaml file and return information

I think we should move the print logic of ModelConfig to its struct member function (ToString() for example) to reduce the code duplication between CLI and controller.

IMO, Model's logic stuffs should be placed in ModelService. In the future, we will need to centralize this ModelService so that we can easily get what model is running (for example). CLI and Http API should just serve as an interface to communicate.
