Eeshan Garg a808f02a22 billing/sponsorship: Allow blank organization URLs.
We ran into a bug in production caused by two issues:
- Some users came from orgs that didn't have a website and since
  the URL field was required, they submitted invalid URLs.
- We didn't properly respond to invalid form submissions, which
  led to UnboundLocalError exceptions in another part of the
  code.

This commit solves this by doing the following:
- We now allow blank URLs and have a convenient placeholder text
  label that tells users that they may leave the URL field blank.
- This commit refactors the code such that invalid form submissions
  result in an informative error message about what exactly went
  wrong.

Vishnu KS 158cec84ec stripe: Upgrade stripe API to 2020-08-27 version.
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

Vishnu KS 50950de24c billing: Void open invoices of small realms without an active plan.
Previously, we only downgraded and voided small organizations behind
payments only if they had an active plan.

This left us with a bunch of invoices from small realms which used to
have an active plan. It doesn't make much sense for us to get these
realms to pay the invoices so we have decided to just void them. This
commit voids the open invoices of all the small realms without an active
plan and has the last invoice open. Unlike, the realms with an active
plan we don't email them about us voiding the invoice. It's not super
obvious whether Stripe sends an email to the customer when the Invoice
is voided. But they do get the message that the invoice is voided if
they try to pay the invoice through the hosted invoice page.

Vishnu KS 292932f3a4 tests: Use expected values list for avoiding duplicate code.
This avoid some duplicate code as well as improve the readability since
before we were checking for the expected values far away from the
definition of realm. Now we define the expected values right after the
realm definition which improves the code readability.
Also, this get removes the postfixing of realm variable names with numbers.
The postfixing is kind of mess since if we want add any new realm in between
the realms we need to renumber a lot of realm variables.

Vishnu KS eee02a3403 billing: Create customer_has_last_n_invoices_open function.
An additional check for whether customer.stripe_customer_id is
None is added to the function. That check was not really required before
since all the customers with a plan also have a valid value for
stripe_customer_id. So all the calls to stripe.Invoice.list would have
non None value for customer argument.

Even though that is the case, mypy should still have complained about
the possibility of customer.stripe_customer_id being None when passed to
stripe.Invoice.list as customer paramater since mypy don't know that
customers with a plan will always have a non empty value for
stripe_customer_id. Our stripe stubs expect a non empty value for
the customer parameter of stripe.Invoice.list. This is despite the
fact that stripe.Invoice.list can actually be called with customer set
to None. This returns the invoices from the entire organization.
Though, we still decided to ensure that the value of customer should be
non empty since there is no reason for us to ever call this function
with customer set to None. You can just call the function wuthout the
customer argument instead. So this requirement of a non None customer
paramater is useful for catching bugs.

The reason mypy didn't complain was because the type of
Customer.objects.all() is Any and not QuerySet[Customer]. So mypy has no
idea that customer.stripe_customer_id can be theoratically None even
though it was not possible in this [articular case as explained before.
I verified that this was the reason mypy didn't complain by using the
reveal_type function on Customer.objects.all() and the customer object.
After the refactoring it's super to obvious to mypy that the type of the
customer is Customer since it's mentioned in the function defintion. So it
was able to complain about the possibility of customer.stripe_customer_id
being None after the refactoring.

This is a prep commit for the Stripe checkout migration.

Vishnu KS 19b25b3fa3 billing tests: Remove unnecessary orjson.dumps of params.
This should have been in https://github.com/zulip/zulip/pull/18066.

The reason, the tests were not failing inspite of the params being
json encoded was because pretty much all these tests did not test
the functionality of the endpoint. Rather they were testing things
like whether the user has the right to access the endpoint and all.
So the value of the params did not matter.

The only one test which is an exception is test_replace_payment_source.
Even though a json encoded token was passed to an endpoint that
expecteda string, the test continued to work becausethe fixtures were
not updated for the test in that PR, so instead of sending an incorrect
json encoded token to stripe endpoint it was sending the correct string
token. Now that we removed the json.dumps of token, we no longer have to
update the fixtures.

I have run the tests with --generate-stripe-fixtures set to True and all
the tests are passing. Not including the fixture changes since the tests
conntinue to work the same with both the existing and new fixtures.

Vishnu KS e0f5fadb79 billing: Downgrade small realms that are behind on payments.
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.

Vishnu KS e64296b3e9 stripe: Create get_all_invoices function.
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.

Vishnu KS 1d579ec567 billing: Fix the type annotation of Customer.stripe_customer_id.
This also fixes a bug in void_all_open_invoices function. If a realm
with a local Customer object but without an associated stripe.Customer
is passed to void_all_open_invoices, then the function will end up
voiding the last 10 invoices created by billing system instead of voiding
no invoices at all. This is because stripe.Invoice.list(customer=None)
return last 10 invoices across all customers.

But this bug won't cauuse any issue in production since
void_all_open_invoices can be only invoked from /support page. And we
show the option to void invoices in support page only if the realm
has a paid plan. And it's not really possible for a realm to have
a paid plan without having an associated stripe_customer_id. Plus I
went through the void events in stripe stream since the PR to add
void invoices was merged and there does not seems to be any suspicious
events.

    - We remove short_name from UserProfile
      and add the appropriate migration.

    - We remove short_name from various
      cache-related lists of fields.

    - We allow import tools to continue to
      write short_name to their export files,
      and then we simply ignore the field
      at import time.

    - We change functions like do_create_user,
      create_user_profile, etc.

    - We keep short_name in the /json/bots
      API.  (It actually gets turned into
      an email.)

    - We don't modify our LDAP code much
      here.

Steve Howell 0b65abcdf5 pointer: Remove pointer from UserProfile.
Most of the changes here are just that we no
longer need to provide a value for pointer
when we create UserProfile objects.

Anders Kaseorg 69c0959f34 python: Fix misuse of Optional types for optional parameters.
There seems to have been a confusion between two different uses of the
word “optional”:

• An optional parameter may be omitted and replaced with a default
  value.
• An Optional type has None as a possible value.

Sometimes an optional parameter has a default value of None, or None
is otherwise a meaningful value to provide, in which case it makes
sense for the optional parameter to have an Optional type.  But in
other cases, optional parameters should not have Optional type.  Fix
them.

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start.  I expect this change will increase pressure for us to split
those files, which isn't a bad thing.
