CORD-628 Refactored VTN service network and port API
- Removed direct use of Neutron data model and Neutron API
- Extended service network and service port API to have all network
information required for VTN
- Removed unnecessary dependency manager and store
- Removed network state sync method with Neutron and XOS
- Removed Neutron and XOS access information from the network config
- Re-organized API packages
