Refactored sr app to enable rest api.

The segment routing application structure has been refactored
to the following structure :
	sr
	 ---- app
 	 ---- web

web folder contains the rest cli implementations while app folder
contains everything else. Originally I tried to split the application
in api / app / web, where api would contain all the interfaces. However,
that was not possible due to the fact that most of the classes do not implement
any interfaces and app -- api would result in circular dependencies and we would
not be able to build them.
