Remove RoutingTableHandler and snapshotter, use database for route stats

- Remove RoutingTableHandler as PrefixHandler maintains live_routes table
- Update server to get route counts from database instead of in-memory routing table
- Add GetLiveRouteCounts method to database for IPv4/IPv6 route counts
- Use metrics tracker in PrefixHandler for route update rates
- Remove snapshotter entirely as database contains all information
- Update tests to work without routing table
