Allow user to configure the category url generation

[nei]

Should it allow the user to choose how the URL will be generated? for instance, if you have two categories with the same name but different category_code I would like to be capable of generating the URLs in Magento based on code and not name.

I believe the change would be here

PIMGento-2/Category/Model/Factory/Import.php

Line 137 in 38012a7

$urlKey = $this->_category->formatUrlKey($row['name']);

I can open a PR for that if we agree with the solution.
