Nat to nat (#146)
* wireguard: export an Endpoint comparison method * Record discovered endpoints in node * Synchronize DiscoveredEndpoints in k8s backend * Add discoveredEndpointsAreEqual * Handle discovered Endpoints in topology to enable NAT 2 NAT * Refactor to use Endpoint.Equal Compare IP first by default and compare DNS name first when we know the Endpoint was resolved. * Drop the shallow copies of nodes and peers Now that updateNATEndpoints was updated to discoverNATEndpoints and that the endpoints are overridden by topology instead of mutating the nodes and peers object, we can safely drop this copy.
