### Context We're looking at implementing plan pricing. While doing so, we encountered a problem with Stripe. **Problem:** when we run a stripe operation (purchase), the product info is encoded as part of the stripe metadata request. Stripe encodes metadata as key-value pairs, and the [value has a limit of 500 chars](https://docs.stripe.com/metadata#data). We do this because once we run the stripe operation, stripe fires a webhook event which is caught by our stripe webhook handler syncStripeSubscriptions. This gets the stripe metadata info from the event and then updates our db in prisma. ### Summary of Changes We add a `ProductVersion` table and only pass the `productVersionId` via stripe metadata instead of the whole product json. This `productVersionId` is created by hashing the `productJson`. Since the same product may be ordered differently without being intrinsically different, we add a helper function for ensuring a canonical order to the json. We also pass tenancy id and product id to the table. Since there are existing subscriptions which used to pass the productJson via metadata, we ensure backwards compatibility.
