public static DriverRemoteConnection using(final Cluster cluster) {
        return using(cluster, DEFAULT_TRAVERSAL_SOURCE);
    }
Creates a {@link DriverRemoteConnection} from an existing {@link Cluster} instance. When {@link #close()} is
called, the {@link Cluster} is left open for the caller to close. By default, this method will bind the
{@link RemoteConnection} to a graph on the server named "graph".
