Terraform always wants to add metadata annotation "run.googleapis.com/launch-stage" = "BETA"

Running terraform plan in either the SSGW Deploy or Deploy Identity project always cause terraform to want to update the launch-stage metadata annotation to BETA.

This seems to be triggered by the fact that both the SSGW and deploy identity project rely on setting the launch stage to beta to allow access to beta features (min-instances and allowed-ingress).

The severity of this issue is minor, in that it just adds noise to terraform plan and apply outputs.
