Currently CheckMetadataConsistency only checks CollectionShardingState entries of namespaces reachable through either the global or the local collection catalogs; other entries are never checked. Therefore we are missing validation that no stale CSS/DSS entries are left.

For example, after dropping a collection, we are missing validation that there are no CSS entries stating that collection exists.
