Description

In flink multi-writer scenario, if one of the writers has no data, it will keep its inflight instant in the timeline. But incremental clean and archive will be blocked by the oldest inflight commit in the timeline.

So to make clean and archive can move forward  we should upport starting a new instant even when there is no data in the last batch.
