Bring back instance & org level support for Datadog CI integration
With release 13.10, we tried to enable the Datadog integration at instance level internally at Datadog and it doesn't work.
Additionally, as reported by @arturoherrero in #284088 (comment 543080333), the feature flag was not hiding the integration at instance level for other orgs, even when disabled. So instance level support was removed in !58702 (merged)
We need to bring this back and make it work properly for customers testing the integration during alpha, and also for private beta. We still won't be ready to remove the feature flag completely for at least another Q.
I don't understand completely how the integrations are inherited automatically from projects to orgs/instances. Hopefully there is a way to fix this in a more reliable way than what we had before. What about adding a new feature flag global to the instance?
