- free trial offers don't need a stripe coupon created for them
- checkout sessions for free trial offers ignore stripe coupon and directly pass the trial days value
- trial days of an offer take precedence over trial days added as default to a tier
refs https://github.com/TryGhost/Team/issues/1519
- Removed offer metadata again from offer (added in one of the previous commits)
- Added `getByStripeCouponId` method in offer repository (required to find an offer based on the stripe_coupon_id)
- Match discounts from Stripe based on the stripe_coupon_id instead of metadata
refs https://github.com/TryGhost/Team/issues/1519
- Added offer repository dependency to member repository (offerAPI didn't work because it creates a new transaction that resulted in a deadlock during tests)
- Store the offer id from the Stripe subscription metadata in the subscription (only if the discount is still active)
- Also added the offer id to the metadata for a Stripe coupon, this will make adding and removing coupons a bit more foolproof
- Prefer the usage of the offer metadata from a coupon if it is present
- When no discount is applied to a subscription, it always sets the offer id to null, even when the metadata still contains the offer
- The offer_id remains stored when a subscription is canceled/expired

We've moved the Stripe Coupon creation out of the Offers module as part
of the work for Stripe disconnect, so we have to make sure that we are
still creating coupons when an Offer is created.

This is a new module which will eventually handle all payment related
things. This allows the Offers module to focus exclusively on the Ghost
concepts, and the Payments module will handle the association between
Offer & Stripe Coupon, Tier & Stripe Product, Cadence & Stripe Price.
This decoupling allows us to not have to consider the lack of Stripe
data for an Offer, which is the case after a Stripe Disconnect. Instead
all of the population/repopulation/lazy-creating can be handled here.
