Ideas:

• api method to get list of collections where storage_classes_confirmed != storage_classes_desired (#17995)
• a way to create a list of all collections stored in one storage class and not on another (#17994)
• a report that provides a list of all blocks stored in a storage class and not another => keep-balance is the only place where we have this information at the moment. Let's punt on this for now.
• deduplication report aware of storage classes (#17993 and #17994)
• keep-balance generates a report on every run. Should we make that more generally accessible? Would be nice but out of scope for this ticket, let's punt on that.
• ... ?
