------------------------------------

    Assignee: Alexey Kuznetsov  (was: Semen Boikov)

Reviewed, fix is not correct, result of ClusterGroup.nodes() should take into account topology changes, this does not work for this 'forDaemons' implementation, here is test reproducing issues:

{noformat}
    public void testForDaemons() throws Exception {
        assertEquals(4, ignite.cluster().nodes().size());

        ClusterGroup daemons = ignite.cluster().forDaemons();
        ClusterGroup srvs = ignite.cluster().forServers();

        assertEquals(0, daemons.nodes().size());
        assertEquals(2, srvs.nodes().size());

        Ignition.setDaemon(true);

        try (Ignite g = startGrid(NODES_CNT)) {
            Ignition.setDaemon(false);

            try (Ignite g1 = startGrid(NODES_CNT + 1)) {
                assertEquals(1, ignite.cluster().forDaemons().nodes().size());
                assertEquals(3, srvs.nodes().size());
                assertEquals(1, daemons.nodes().size());
            }
        }
    }
