Rename spring.task.execution.shutdown.await-termination to align with setWaitForTasksToCompleteOnShutdown

spring-boot-2.6.6

I want my @Async tasks to delay a shutdown.

application.properties:

server.shutdown=graceful
server.shutdown.grace-period=30s
spring.task.execution.shutdown.await-termination=true

@SpringBootApplication
@EnableAsync
public class AppConfiguration {
	public static void main(String[] args) {
		SpringApplication.run(AppConfiguration.class, args);
	}
}

@Service
public class AsyncService {
	private final Logger LOGGER = LoggerFactory.getLogger(this.getClass());

	@Async
	void runAsync() throws InterruptedException {
		LOGGER.info("Starting async job...");
		TimeUnit.MINUTES.sleep(5);
		LOGGER.info("Async job finished.");
	}
}

@RestController
public class MyController {
	@Autowired(required = false)
	private AsyncService async;

	@GetMapping("/async")
	public String async() throws InterruptedException {
                LOGGER.info("Async servlet accessed");
		async.runAsync();
		return "Async process started in background. Please shut down the application now!";
	}
}

Use the application.properties example and the @Async reproduction as entry points. Locate the Spring Boot task-execution shutdown property definition and its tests, then verify the renamed property aligns with setWaitForTasksToCompleteOnShutdown while preserving delayed shutdown behavior. Done means the naming is updated and the async shutdown scenario is covered.
