IShutdownServiceDelayedShutdownToken Property

Gets a cancellation token that gets signalled a couple of seconds after the ShutdownToken. This cancellation token may be used to stop background calculations that should run for a limited time after the application is closed (e.g. saving state in caches - work that should better run even though we're shutting down, but shouldn't take too long either)

CancellationToken DelayedShutdownToken { get; }
