Debug Output

https://gist.github.com/bskaplan/560b83679746aa53fdd6ff24f8b89cdf

Expected Behavior

Test should have completed successfully

Actual Behavior

There was an unexpected diff in effective_annotations for run.googleapis.com/launch-stage

Steps to reproduce

1. terraform apply a service with a feature that is in beta and set the annotation run.googleapis.com/launch-stage: beta.
2. update the cloud_run_service config to not depend on any beta features and terraform apply again

Important Factoids

The launch-stage annotation in Cloud Run is a bit weird. On input, it represents the launch stage that you want to allow for new features. The server will respond with the launch stage required for the features used. So if you deploy with launch-stage: BETA but do not use any beta features, the launch stage annotation is removed from the response.
