[PATCH 4/5] Move fence_kdump nodes filtering into separate function

[Martin Perina]

Move fence_kdump nodes filtering (they cannot contain `hostname`) into
separate function get_list_of_nodes_to_notify. This will be also used by
generic cluster fence_kdump configuration introduced in following patch.
