- Move `util/grpc` and `util/net` to `client` so `internal` packages can be accessed - Add methods to return the next best interface after the NetBird interface. - Use `IP_UNICAST_IF` sock opt to force the outgoing interface for the NetBird `net.Dialer` and `net.ListenerConfig` to avoid routing loops. The interface is picked by the new route lookup method. - Some refactoring to avoid import cycles - Old behavior is available through `NB_USE_LEGACY_ROUTING=true` env var
