RFC: ease simple product CSV/XLS import

[rvalyi]

What about this in product_usability?

add a product.product menu in inventory settings?

to import all fields, you need to pass through the product.product menu. While in 90% of the cases we disables product variants.

product.template external ID utility

so once the power user imported the catalog using a product.product menu, what happens is that product.product records do have an external ID, but product.template records don't. But often you may have other related things to import (say secundary product unit) and these other objects can be carried by the product.template instead of the product.product so it's currently not easy for the user to import these things later...

What could we do? Have a button to populate the product.template external ids from the product product ones?

a bit related to https://github.com/akretion/pattern-import-export but may be we can have basics things here.

so in fact after importation product.template records do have external ID. So this second point is a non issue.

another thing we may need is a simple way to define an external ID for an existing record (without the need to go to the ir_model_data as an admin) and without being able to destroy all. Use case: customer need to create just 1 o 2 new categories before doing a product import. Importing a categ XLS seems overkill.
