How to test

1. Trigger a custom Werft build (using the config from this PR)
   • E.g. like so: kubectx dev then werft job run github -j .werft/build.yaml
2. Once built, in the preview, create a team called "Gitpod" (or any team name containing the word "Gitpod")
3. Go to Team Settings > Team Billing
4. Wait for the Usage-Based UI to show up
5. Subscribe to Usage-Based Billing by entering a credit card (e.g. 4242 4242 4242 4242, 4/24, 424)
6. Wait for the Stripe subscription to be created
7. Once you can, click on "Manage Billing"
   • Your subscription should be linked to a product called Gitpod Usage (with latest prices)
8. Start a workspace
9. Wait for one hour (or manually trigger a usage report*)
10. Go to the Stripe dashboard > Customers > (your created test customer) > click on the Subscription
11. The "Upcoming invoice" should show some credits (with the first 50 credits being free)

LGTM, haven't executed the steps in the PR but will take a look in the evening.

Going through the manual test steps worked as intended! 🎉 Proof:

Step 7

Step 11

Double-checking the credits math

• I ran 5 workspaces for just over 9 minutes each ≈ just a bit over 45 minutes of total usage
• The latest usage report had:

[{"team_id":"4becf0d4-5a12-430c-89cf-96c5549b8aec","workspace_seconds":2813}]

• 2813 seconds / 60 ≈ 46.88 minutes
• 46.88 minutes / 6 ≈ 7.8 credits
• rounds up to 8 credits 🎉
