Beschreibung
It seems reasonable to support a memory parameter to FeatureUnion like was recently added to Pipeline (#7990). It is valuable in the sense that parameters in some constituent transformers can be searched over while others are unchanged; those that are unchanged should not need to be re-fit from scratch.
