[SUPPORT]How to continue an unfinished compaction task

[wqwl611]

I manually interrupted a compaction task，and then started one HoodieCompactor task again，but I got one FileAlreadyExistsException.

I konw I can manually delete the file, but I wonder more convinent way?

I kind of remember, we already introduced auto rollback for HoodieCompactor since release 0.14.0, but before that, you can only rollback the compaction task with Hudi CLI.
