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.
I think it is probably better if there is a one_shot_query/5 with a timeout argument. The mechanisms are already in place there for a proper query timeout.
