Idea #18256

* Investigate orchestration
Certain configuration steps have dependencies on configuration of other nodes, which requires orchestration rather than just top-down configuration.
e.g. need to know how to contact postgres
Javier: want bottom-up configuration, when services come up they contact the configuration server (consul?) to get the configuration & update the service entry.
Tom: "join" command (state?) to add a service to Arvados
Use pre-shared key / token for machines to identify themselves. Or nodes generate their own random ID and there's an approval step.
Tom: would be cool if nodes can self-configure which services they run
"Join" state gets a list of services that node with this unique ID should be running, can be changed on the fly.
Stephen: could have a discovery mode
Ward: restrict to private network
Javier: Controller should hold the central configuration
