> This change proposes to add a *parallelismConfigured* property as a flag to
> identify whether the parallelism of node is used "parallelism.default" or
> not. If the vertex's *parallelismConfigured* is true, the
> AdaptiveBatchScheduler will not automatically deciding parallelisms for it.
> Otherwise, AdaptiveBatchScheduler will automatically deciding parallelisms
> and use the "parallelism.default" as an alternative value for the
> "jobmanager.adaptive-batch-scheduler.max-parallelism".
> This change will make user do not need to configure "parallelism.default" as
> "-1" to automatically deciding parallelisms for vertices.
