[IMP] product: add product tag model

This commit adds the product tag model.

Purpose
=======

The product tags allows to easily tag given types of product
independently from their category, following their product range, their
seasonal collection, their theme, etc

Specification
=============

A product template takes tags that are valid for all their variants.
In order to add granularity, product variants can also take additionnal
tags.
A field is defined on product variants to allow searching on both
product template and product variant tags.
