Missing product fields in query Order > Lines > ProductVariant

[jonyw4]

Problem

Some crucial fields on Order.Lines.ProductVariant are missing, like slug and optionGroup.name and optionGroup.code. I use these fields to create a product link, so i think that fields are really important to user navigate in the storefront

Solutions

Add these fields in Order.Lines.ProductVariant or maybe create a Product field in this resolver to user choose witch fields they want to query.

[michaelbromley]

The simplest solution here is to define a ProductVariant.product field and an Option.group field respectively.

However, there is a danger involved here as we now have some new recursive types, e.g.

product {
  variants {
    product {
      variants {
        product {
          id
        }
      }
    }
  }
}

This creates a risk described in #381

The alternative of storing these values directly on the OrderLine entity removes that risk, but is inelegant as this is data that should be derived from live values, and is kinda the point of GraphQL in the first place.

I think the way forward is to solve 381 and then implement the fields & resolvers.
