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
