Pull request overview
This PR aims to prevent the periodic VM/Volume stats cleanup background tasks in StatsCollector from being permanently stopped when a cleanup run throws an exception (per #13648).
Changes:
- Wrapped
VmStatsCleanerandVolumeStatsCleanercleanup calls in try/catch blocks to avoid uncaught exceptions escaping the scheduled task. - Added unit tests for volume stats cleanup enable/disable behavior and for cleaner exception handling.
