PDP Variant Layout UX update

[aaronjudd]

With inventory updates we'll not be automatically updating inventory qty for variants with children.

This leads to a UI refactor, but rather than just replacing the inventory logic, we should update the product detail page.

• Move variant control/setting template into the admin side bar.
• Simple Product View -
  Products without Variants #500 with a "single variant / simple product view"
• Variants (with children) with images.
• Variant / Option View dropdown selector, with images.

This is HUGE. So looking forward to this UI update, something we discussed adding internally a few times @getoutfitted but have held off on so far.

I will shed a few tears to see my progress bars gone ;-)

We will all mourn the loss of the progress bars. 😢

Closing - insufficient details.
