This PR adds a new `POST /billing/subscriptions/manage` endpoint that
can be used to manage a billing subscription.
The endpoint accepts a `github_user_id` to identify the user, as well as
an optional `subscription_id` for managing a specific subscription. If
`subscription_id` is not provided, it try and use the active
subscription, if there is only one.
Right now the endpoint only supports cancelling an active subscription.
This is done by passing `"intent": "cancel"` in the request body.
The endpoint will return the URL to a Stripe customer portal session,
which the caller can redirect the user to.
Here's an example of how to call it:
```sh
curl -X POST "http://localhost:8080/billing/subscriptions/manage" \
-H "Authorization: <ADMIN_TOKEN>" \
-H "Content-Type: application/json" \
-d '{"github_user_id": 12345, "intent": "cancel"}'
```

This PR adds a new `POST /billing/subscriptions` endpoint that can be
used to initiate a billing subscription.
The endpoint will use the provided `github_user_id` to look up a user,
generate a Stripe Checkout session, and then return the URL.
The caller would then redirect the user to the URL to initiate the
checkout flow.
Here's an example of how to call it:
```sh
curl -X POST "http://localhost:8080/billing/subscriptions" \
-H "Authorization: <ADMIN_TOKEN>" \
-H "Content-Type: application/json" \
-d '{"github_user_id": 12345}'
