        Specified by:
        shutdown in interface Shutdownable
        Parameters:
        shutdownManager - provides toolset to get a Future for a shutdown of instances that have both non-blocking and not returning a Future on a completion shutdown methods (like ExecutorService.shutdown())
        interruptTasks - if the threads processing user code (like workflows, workflow tasks or activities) should be interrupted, or we want to wait for their full graceful completion
        Returns:
        CompletableFuture which should be completed when awaiting downstream dependencies can proceed with their own shutdown. Should never be completed exceptionally CompletableFuture.exceptionally(Function) as downstream dependencies have no use of this information (they need to perform a shutdown anyway), and it complicates the shutdown flow.
