Doc Text:	.Users can remove cloned objects after upgrading a cluster Previously, after upgrading a cluster from {storage-product} 4 to {storage-product} 5 , removing snapshots of objects created in earlier versions would leave clones, which could not be removed. This was because the `SnapMapper` key’s were wrongly converted. With this fix, `SnapMapper`’s legacy conversation is updated to match the new key format. The cloned objects in earlier versions of Ceph can now be easily removed after an upgrade.	Story Points:	---
