func lookup(_ service: Service, deadline: DispatchTime? = nil) async throws -> [Instance] Performs async lookup for the given service’s instances.
func subscribe(to service: Service) -> ServiceSnapshots<Instance> Returns a ServiceSnapshots, which is an AsyncSequence and each of its items is a snapshot listing of service instances.
