This is a major rewrite of the billing system. It moves subscription
information off of stripe Subscriptions and into a local CustomerPlan
table.
To keep this manageable, it leaves several things unimplemented
(downgrading, etc), and a variety of other TODOs in the code. There are also
some known regressions, e.g. error-handling on /upgrade is broken.
The fixture changes are because self.upgrade formerly used to cause a page load
of /billing, which in turn calls Customer.retrieve.
If we ran the full test suite with GENERATE_STRIPE_FIXTURES=True, we would
likely see several more Customer.retrieve.N.json's being deleted. But
keeping them there for now to keep the diff small.
This will change the hash of the URL when a new tab
gets selected. Vice versa when the billing page is opened
the appropriate tab is selected according to hash of
the URL. This means when the card gets updated the
page would be reloaded correctly to show #payment-method
tab.
The actual implementation of the change will be a cron job that runs once a
day and generates invoices for anyone with an account_balance > 0.
There are currently no tests for that part of the flow, so no tests had to
change.
