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 thought there were two different values, a frequency for polling and a query request timeout. This value should be named a frequency, not a timeout. I suppose it is ok to make the timeout on the peer query 90% of the frequency, but reply requests are typically much shorter and controlled by the request reply timeout.
