Payment portal should allow EE license to be purchased at same time as instance
This may require integration of the GitHost stripe account into our general Zuora account.
Basically, on our end, we always need to be able to see the distinction between charges for / payments for license vs. usage. Usage is billed monthly since it can fluctuate, licenses billed annual. In #30, at least one customer asks for an easy way to add users on the fly. That's perhaps one step too far at the moment?
@rdavila can you help us format the payment portal and process so that everything is easy for the customers with a single credit card swipe?
