Manually deleted consuming segments #9039
Description
PR #8663 adds a new endpoint to recreate consuming segments which have been deleted manually by admins. Now this resume endpoint is used in pause/resume consumption in PR #8986
@mcvsubbu brought up a good point that we can block deleting consuming segments in segment deletion endpoint. If we do this, then periodic RealtimeSegmentValidationManager job - which ensures all partitions are properly consuming - can only fixes the issues that might happen in edge cases of commit protocol and not fix the user errors. This will simplify the code on the periodic job.
