Related to #14131, #14634, and #14639. ### Description Split the SegmentNukeAction into smaller batches. The segment nuke runs inside a critical section inside the `TaskLockbox`. This blocks up most activity in the overlord, including allocation of new segments, while the nuke is running. If the nuke runs for a long time, it can cause issues with cluster stability. This change relieves pressure on the `TaskLockbox` by splitting the nuke work into smaller chunks, which will allow other tasks to interleave with the lockbox. ##### Key changed/added classes in this PR - `SegmentNukeAction`: partition the segments into batches of size 1000 for nuke. <hr> This PR has: - [x] been self-reviewed. - [ ] added unit tests or modified existing tests to cover new code paths, ensuring the threshold for [code coverage](https://github.com/apache/druid/blob/master/dev/code-review/code-coverage.md) is met. - [ ] been tested in a test Druid cluster. -- This is an automated message from the Apache Git Service.
