> Support to send StreamStatus.IDLE for non-source operators

> Key: FLINK-11286

> Project: Flink

>
> Currently, only stream source tasks can be marked as temporary idle. But many
> times, this approach has limitations.
> Considering such a scenario, there is a DAG as follows:
> {{source->map->filter->flatmap->keyBy->window}}, with a degree of parallelism
> of 10. Among them, the watermark is not sent by the source operator, but is
> downstream, such as flatmap. Every source subtask will not be idle. However,
> after the filter, some pipelines generate "idle". For example, there are 3
> pipelines that will no longer have data sent downstream. At this time, we
> can't call the {{markAsTemporarilyIdle}} method to mark the current pipeline
> in the idle state. This will affect the downstream window.
