The previously configured never-expiring coupon does not refill every
month. Eventually, even though it never expires, it will run out. This
commit makes several small changes to address this issue for the free
tier:
* Change the config for the promotional coupon to be $1.65 for 1 month
(the change from $10 to $1.65 is due to our recent pricing changes)
* Update PopulatePromotionalCoupons (PPC for brevity) to add promotional
coupons to users with expired and consumed coupons (all users with a
project and no active coupons should get a new coupon when PPC is called)
* Call PPC at the end of the `create-invoice-coupons` stage of invoice
generation - after current coupons are processed and expired/exhausted.
* Remove legacy admin functionality for PPC from satellite/console - we
do not currently use it, but if we did, it should be in satellite/admin
instead.

* 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.

This change is removing ProjectID from code. Next change will be about
dropping this colum from DB table.
