Supporty for the StoreFront GraphQL API

[aprueser]

There are a few issues logged back in history requesting the addition of the StoreFront endpoints. Comments indicate that this may have at least been thought about. Did anything ever come to fruition that hasn't made it into a release.

Hey! That's a good question; for a long time I hadn't considered the StoreFront API to be "in scope" for this project as it required javascript on the actual storefront to use it. Then over time Shopify introduced additional access token modes that allow us to use it from the server too, as we have today.

So long story short, I do want to add support for it! As soon as I merge #1051 this week (working on it today) I'm going to update this project with my wants and goals for improving ShopifySharp's GraphQL support.
