Wishlist Feature

### User Story

As I user I want to use whishlists to manage products with my personal touch.

### Description & Motivation

The ability to create/edit/delete different wishlists is crucial to offer the user a pleasant commerce journey. The user should be able to add/remove/update products to the desired wishlist organizing the cluster of products as preferred.

### Deliverables

As far I can see the feature is missing so it requires all kind of development tasks.

### Acceptance Criteria

Components should support all CRUD operations (create, read, update and delete) to customize/handle wishlist itself.
Components should support all CRUD operations (create, read, update and delete) to manage products of wishlist.

No files, tests, or entry points are identified. Start by mapping the existing component and product-management structure, then define the scope for wishlist CRUD and product membership operations; done means both wishlist objects and their products support the specified create, read, update, and delete behavior.
