Generalize IntentSynchronizer and separate reactive routing code
* IntentSynchronizer can now handle any intent rather than having use
case specific APIs
* IntentSynchronizer does not generate or store intents anymore, it only
perform synchronization
* SdnIpFib generates and manages the procative route-based intents
* ReactiveRoutingFib generates and manages the reactive intents
* Unit tests have been tightned up to only test single components, rather
than multiple components together
* PeerConnectivityManager uses meaningful keys when creating intents
