Marketplace VM solution - investigate - 0.X.N - automate Cloud Run domain name mapping

[swilliams11]

Can we perform the following actions automatically?
1.
Domain name mapping for the Cloud Run API - confirm that this can be automated
Domain name mapping for the Cloud Run UI - confirm that this can be automated

2. This step can be completed, but it is only useful in the context of the first step above.
   In VM startup script check that the domain is verify that the user owns the domain by executing the gcloud verify command with the current user; if this command fails, then fail the deployment, otherwise allow the deployment to continue.
