Description

Like with collections, we can never be sure we've exhausted all the sstables when reducing the filter. The sstables can contain legacy local shards that need to be summed up. Unless we look into the content of the cells , or until we get rid of the pre-2.1 values, we must include all the sstables in the read (so long as clusterings overlap).

This was not an issue with 2.1/2.2 as we've forced collectAllData always on that path, but now we don't, and SinglePartitionNamesCommand should handle the case.
