class ProjectionRegistryActor extends Actor with ActorLogging

Build an in-memory, CRDT-backed representation of the status of each projection worker. Each instance of this actor communicates with the 

WorkerCoordinator

running locally to propagate requests and retrieve status of the actual worker actor. The retrieved data for requested and observed status is propagated to other peers.
