[Docs] Overview of different programming styles and techniques supported

[mitsos1os]

Suggestion

Different programming styles supported by LoopBack should be better described (controllers instantiated per request, controller singletons, etc.) and explain the pros and cons of each approach, so that users can make an informed decision about which style to use in their project.

Singleton controllers should be a first-class well-documented feature.
