Define the new Intent Framework APIs (Intent Service)
- Define the base Intent class and sub-classes required in SDN-IP
- IntentService provides the APIs for application developers
- IntentExtensionService enables to define application specific intent types
- Provide event handling mechanism via IntentEventListener
This is for ONOS-1654.
