[IMP] product,(website_)sale: Move product options configurator into sale module

Task #1871557

Purpose
=======

- Configure a product from a sales order as easily as in the ecommerce
  The backend uses the same template as the frontend to configure a products and its options

- Display optionnal products of optionnal products in the "sale options" section

- Allow adding exlusions to some combinations of the product and/or
  to some combinations of the optionnal and accessory products

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

PHASE I

1. Improve the "Add to cart" with optional products

- When you add an option to cart, move the product to the cart & show the options of this option
- Don't open the option wizard if no option available (in case this module becomes generic,
  it's better to skip this step when it's not needed)
- Display the options right under their related product in the cart

2. Do not allow to add the product as an optional product for itself
Why ?
- No functional sense
- Creates issues in the add to cart wizard

3. Exclude some attribute combinations within the product or with related options and accessory products

- Rename VARIANT PRICES button -> CONFIGURE VARIANTS
- When you click this button and select a value, open form view rather than inline edition
- Form view of variant values:
	- Attribute
	- Value
	- HTML Color Index
	- Attribute Price Extra
	- Not Compatible with: o2m tab with 2 fields: Product AND Attribute Value (of this product)
	  [m2m tag selection]
	- in any new line, autocomplete the current product by default
	- Tooltip: A list of product and attribute values that you want to exclude for
          this product's attribue value. Also applies on optionnal and accessory products.

4. New option to configure a product in a sales order line

- This option is only visible if the corresponding option is activated in the sales settings
- It opens a wizard to select a product template, configure related attribute values
  and select optional products (based on frontend view)
- Attributes not compatible with other selected attributes should not be selectable
- Must work like in the frontend
