COOL-613: Add categories property to the supermarket upload method.

[TheLunaticScripter]

When running Automate 0.5.1 with ChefDK 0.16.28 on a disconnected network I had an issue where when publishing a cookbook to the private supermarket publish would attempt to go the public supermarket unless a category was specified. This pull request fixes this issue by adding a property for categories to that library. This problem appears also be fixed by upgrading to ChefDK 0.18.30. In order to fully utilize this property I believe the delivery-truck cookbook will also need to be updated.

@TheLunaticScripter I could have sworn I poked someone internally on this. Let me go see what I can do.
