public interface LiveOperationsTracker
Can be implemented by a Service to track live operations. This functionality is needed to let the executing side
 inform the caller side which operations are still running. If an operation doesn't provide a heartbeat, the caller
 can eventually decide to timeout the operation.
 Some operations are not executing on regular operation threads (e.g. IExecutorService) or not running at all
 (blocking operations).
