Earlier, for fixed-price plans we were showing the generic
next payment info on billing page which stated that plan
will automatically renew on end_date. It is no longer correct
for fixed-price plans.
This commit fixes the next payment info for fixed-price plans.
When the next_billing_cycle is the end_date, we inform the customer
that their plan will end on end_date and zulip sales will contact
them a couple of month ago before the end_date for renewal.
Adds a link on the upgrade and billing pages that opens a stripe
billing portal for the customer to update their name and address
that will appear on invoices and receipts.
On the billing page, updating the credit card information will
no longer update the customer billing address, since they can
now do this directly through the billing portal. To be consistent
with the credit card form on the upgrade page, we still require
inputting a billing address for the card.
Note that, once an invoice is paid/complete, then changes to the
customer's name and address will not be applied to those invoices.
Instead of charging the customer using the attached payment
method and then creating the invoice, we create an invoice and
force an immediate payment for the invoice via the attached
payment method.
