Finish Subscriptions

[goshlanguage]

We should define acceptance criteria for the addition of a service, and adhere our Subscriptions service to this model.

Per our meeting (Oct 5), we've discussed supporting latest API +1 for each service.

We consider completeness as all routes implemented.

Big yikes. I believe we have misunderstood the way that Azure SDK versions its APIs. While approaching this for subscriptions, it looks as though the routes are additive, instead of being different versions of the same API routes/functions.

We may not be able to simply do latest version +1 support. In this example, this would mean not supporting the List route for example.

The remaining subscriptions work is as follows:

Routes:

• List
• Subscription Factory
• Subscription Operation List
• Create CSP Subscription
• Create subscription
• Subscription Operation Get
• Cancel
• Enable
• Rename
