Enterprise Program API support

[barakwei]

Apple has recently released the Enterprise Program API, which lets users automate tasks in their enterprise team. The API has its own OpenAPI spec, server etc, and it's probably 90% a subset of the App Store Connect API.
Do you have any thoughts about how the Enterprise Program API relates to this repo? Should it be in another package/repo or a part of this one? should it share the same objects?

I don't have any plans to add it myself, but if integrate well as a separate target in this package, I think it makes totally sense to add it to this repo!
