face: FaceSystem class

FaceSystem class is the entry point of NFD's face system. It owns
ProtocolFactory objects that are created from face_system section of
NFD configuration file. This responsibility is split from FaceManager.

This commit also adds test coverage for face_system.websocket config
section processing routine.

refs #3904
