coreshop#1613 TagManagerEnhancedEcommerce

fixing some of the listed issues in the ticket
Fixed:
- trackCheckoutComplete - Rename total to revenue
- trackProductImpression - remove quantity, brand, position, attribute
- trackCartAdd - quantity is hardcoded to 1. Use $quantity instead

Template issues
- product_impression.js.twig
- product_view.js.twig
- checkout.js.twig
- checkout_complete.js.twig

Not fixed:
- trackProductImpression - submit impression as multi- instead of single-array
- trackCartAdd - price attribute: I'm not sure about that but I think we need to use the cart item price instead of product price (which often can't be determinate (because of complex variant structure etc.)
- trackCartRemove
