Disable generation validation on commit

When doing a full sync & commit, we want to be sure that all record types are committed. Take for instance a case when a last grouped product was removed from the catalog. There are no other grouped products, so there is nothing to be committed indeed. However, we want to make sure that remaining grouped products are removed from Luigi's Box as well. The validate_generation: false parameter ensures that.

Better support for configurable & grouped products

There are three types of products in Magento. Product, SimpleProduct and GroupedProduct.

SimpleProduct is most often linked to a Product (which acts as its config). SimpleProduct can be seen as a particular variant of a Product (of a particular size and/or color).

However, there might be a SimpleProduct, which is not linked to any Product and can be bought separately.

Before this commit, all products were synced separately. However, we need all SimpleProducts which do have their Product to be grouped together and synced in one record, where SimpleProducts are nested as "type:variant".

GroupedProducts are synced accordingly, but instead of "type:variant", they are nested with "type:member".
