   Background job sounds good to me. We can build it similar to reload job.
   There is another issue we want to address: we delete segments from deep store and ZK metadata separately. If controller crashes after ZK metadata is deleted, but before segments are deleted, the segments will left orphan, and rerun the table deletion won't be able to find the segments. The fix should be always first delete the segment from deep store, then delete the ZK metadata for each segment
