* Add a nullable billing_periods column in the coupons table
* Add nullable billing_periods column to the currently unused
coupon_codes table
* Drop the duration column from the coupon_codes table
* Replace duration config type so that the default promotional coupon
can be configured to never expire
Zero downtime migration plan:
* Add billing_periods column to coupons and coupon_codes tables (this change)
* After one release, remove all references to the old duration column,
replacing with references to billing_periods. At this point, we can also
change the defult promotional coupon to never expire and migrate over
values from the old duration column.
* After another release, drop the duration column.

We are implementing the free tier, which will give all new users 3
projects, 50gb storage, and 50gb bandwidth per project. All users will
receive a recurring coupon to cover this amount of usage.
With the free tier, we no longer need a paywall. Users will not need to
enter a payment method unless they want to increase their project or
usage limits.

Add a config so that some percent of users require credit cards /
account balances
in order to create a project or have a promotional coupon applied
UI was updated to match needed paywall status
At this point we decided not to use a field to store if a user is in an
A/B
test, and instead just use math to see if they're in a test. We decided
to use MD5 (because its in Postgres too) and User UUID for that math.
