Decommission the snowflake-reg-test.appspot.com reflector
snowflake-reg-test.appspot.com is a frontend for snowflake-broker.bamsoftware.com, briefly used with a Google domain front. It never actually worked, because this was around the time that Google stopped domain fronting.
On 2020-02-05, arlolra and I got an email saying that we needed to upgrade the deployment to the Go 1.11 runtime by 2020-05-01. I tried doing that today, but got the error
ERROR: (gcloud.app.deploy) Error Response:  Access Not Configured. Cloud Build has not been used in project snowflake-reg-test before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/cloudbuild.googleapis.com/overview?project=snowflake-reg-test then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.
I tried doing that, but apparently there is no truly free tier anymore and you can't deploy or redeploy apps without setting up a billing account. Rather than go through with that, I propose that we just disable the unused service.
