### Description To help prevent the metadata store from growing unbounded, enable kill unused segments by default on all datasources. This is helpful when users have auto-compaction running or they age out data. The old segments are marked as unused but live on in the metadata store and in deep storage. The new defaults should kill all unused segments older than 90 days. If users do not want this behavior on an upgrade, they should explicitly disable the behavior, or change the specific datasources they would want to run on. <hr> This PR has: - [x] been self-reviewed. - [ ] added documentation for new or modified features or behaviors. - [ ] added Javadocs for most classes and all non-trivial methods.
