TS-938 - Don't merge

Adding the config and a gen_server to handle the c* nodes. But this uses elysium 0.1.7 so the files changed are really misleading.

Also the query seems to work, but it is not currently being used.
one alternative is to use {ok, State, 0} to triger handle_info immediately. then start update_nodes() there and set a timer afterwards for new update
