This upgrades the Stripe API to the most recent version. Going through
the Git history, it looks like our current API version is at 2019-03-14.
The API version should be manually changed in Stripe dashboard at the same
time as the commit is deployed in production.
Backward incompatible changes that are relevant to our codebase between
(2019-03-14, 2020-08-27].
* 2020-08-27 - The `sources` property on Customers is no longer included by
default.
* 2020-03-02 - Nothing applicable
* 2019-12-03 - The `id` field of all invoice line items have changed and are
now prefixed
with `il_`. We only rely on this while we normalize the fixtures.
* 2019-11-05 - Nothing applicable
* 2019-10-17 - The `billing` attribute on invoices, subscriptions, and
subscription schedules is renamed to`collection_method`. The invoice
change is the one that is relevant to us.
* The customer object’s `account_balance` value has been renamed to
`balance`. Only used for the stubs at the moment.
* 2019-10-08 - Nothing applicable
* 2019-09-09 - Nothing applicable
* 2019-08-14 - Nothing applicable
* 2019-05-16 - Nothing applicable

Also normalize the following IDs in stripe fixtures
* price_[A-Za-z0-9]{24}
* prod_[A-Za-z0-9]{14}
* pi_[A-Za-z0-9]{24}
* il_[A-Za-z0-9]{24}
An organization with at most 5 users that is behind on payments isn't
worth spending time on investigating the situation.
For larger organizations, we likely want somewhat different logic that
at least does not void invoices.
stripe.Invoice.list by default would only get 10 invoices at a
time. So a function like this would be really handy if we have
to go through a lot of invoices.
This also means void_all_open_invoices used to void only the last
10 invoices. The main reason we implemented this function was to
void the invoices generated by realms on free trial so I don't
think there were cases where we had to void realms with more than
10 invoices.
mypy in daemon mode takes some 400 MiB of memory, and cannot follow
imports of type-annotated third-party packages; meanwhile, non-daemon
mode is no longer nearly as slow as it once was.

Previously, when users got a "payment failed" email from Stripe (e.g. if
their card failed on renewal), they would enter in a new card on
/billing#payment-method, and wouldn't find out if the card worked till
Stripe retried the payment 4 days later.
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.
Also fixes a bug in process_initial_upgrade. If you have a card on file
(e.g. from a previous subscription), and try to upgrade by billing by
invoice, neither the if nor the elif condition applies.
This will make it easier to mock the calls in our new stripe mocking
framework. I believe the two forms are equivalent, assuming the Stripe
Python bindings aren't doing anything crazy. And if not, well hopefully our
new testing framework will catch it :).
[Idea originally from Vishnu KS.]
This will improve both the maintainability and accuracy of the fixture
data. It also makes it less scary to upgrade Stripe API versions.
[With significant changes by Rishi Gupta.]
There are several situations in which we want to create a Customer and
stripe.Customer object before we really have a billing relationship with a
customer. The main one is giving non-profit or educational discounts.
