      Description

      An oplog observer running on shard secondaries watches for writes to collection admin.system.version, document startRangeDeletion.

      On detection, calls CollectionShardingState::overlappingMetadata, and passes the result to CursorManager::invalidateDependent, which calls markAsKilled on affected queries.
