Research direction

Begin with the server startup configuration flow described in the issue and determine how coordinator, ZooKeeper, or etcd would provide the shared configuration. Define how periodic synchronization, application to the config map, and a configuration hash or version should work. Done means all servers and clients can obtain common configuration from one center and refresh it reliably.
