Рефакторинг системы вариативных товаров и справочник атрибутов

Browse Source 
Основные изменения:
- Переименование ConfigurableKitProduct → ConfigurableProduct
- Добавлена поддержка Product как варианта (не только ProductKit)
- Создан справочник атрибутов (ProductAttribute, ProductAttributeValue)
- CRUD для управления атрибутами с inline редактированием значений
- Пересозданы миграции с нуля для всех приложений
- Добавлена ссылка на атрибуты в навигацию
