Which actions should be used to clean up and maintain Iceberg metadata?

• expireSnapshots: Is it recommended to delete old snapshots using the same retention period as the Delta table?

• deleteOrphanFiles: This deletes unreferenced Iceberg metadata as well as unreferenced data files. Is it safe to run this when some data might still be referenced by Delta metadata?

• rewriteManifests: This action rewrites manifest files for optimization but also creates a new snapshot. Should this be executed?
