Earlier, the 'self.on_paid_plan()' check was verifying if the
billing_session/customer is on paid plan and not the plan we
are processing.
This resulted in a bug. While processing a legacy plan, a customer
switches from legacy plan to a paid plan resulting in the
'self.on_paid_plan()' check returning True.
It leads to invoicing legacy plan which shouldn't happen.
The fix is to check if the plan we are processing is paid or not
instead of the remote_realm/remote_server plan_type.
For fixed-price plans, we send a reminder email to
sales@zulip.com, 2 months before the end date, to review
the pricing and configure a new fixed-price plan accordingly.
Earlier, we were not configuring the end_date while creating
a fixed-price plan which would result in the automatic renewal
of the plan at the end of billing cycle.
Our plan is to re-evaluate the pricing when we are close to the
end date, then:
1. Schedule a new fixed-price plan with the updated or same price.
2. or Don't do anything - the plan will end on the end_date.
Now, we add an end_date of 1 year from the start date when
creating a fixed-price plan.
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.
Now that a customer discount may require a particular plan tier to
be applied, update the billing code to check the plan tier when
getting the customer default_discount field/information for a new
plan.
For billing schedule changes and displaying billing information for
current plans, we explicitly use the discount set on the current,
active plan and do not check the customer object for these actions.
This will be used to set a required plan tier value to be used with
the default discount that is set on the Customer object or with a
fixed price set on a CustomerPlan object.
Also adds `SWITCH_PLAN_TIER_AT_PLAN_END` for `CustomerPlan`
which will be used to mark status of remote server legacy
plans which are scheduled for an upgrade.
Since Customer already stores the realm it is linked to and
customer is always created to store sponsorship request, we directly
use customer to link to the sponsorship data for the realm.
Renames CustomerPlan.SWITCH_NOW_FROM_STANDARD_TO_PLUS to be more
generic, CustomerPlan.SWITCH_PLAN_TIER_NOW.
Because the plan tier change is immediate, moves the code to end
the current plan with the old tier and create the new plan with
the new tier from `make_end_of_cycle_updates_if_needed` to instead
be in a separate helper function, `switch_plan_tier`.
If the update / add card session is successful, return user to
manual license management page if user was on it before clicking
the add / update card button.
These new models are incomplete and totally untested, but merging this
will provide valuable scaffolding for doing smaller PRs working on
individual gaps, and reveals a clear set of TODOs/refactoring/model
changes needed to support where want to end up.

The Django convention is for __repr__ to include the type and __str__
to omit it. In fact its default __repr__ implementation for models
automatically adds a type prefix to __str__, which has resulted in the
type being duplicated:
