Actual Behavior

DIdn't appear to change google forwarding rule at all. Plan still shows desired change as well.

1. Config to look like first snippet
2. terraform plan
3. Config to look like second snippet
4. terraform plan to see change
5. terraform apply to attempt change
6. terraform plan to see failed change still pending

Closed via #13833

[owensk]

This will now just fail on apply per #13823. At least, this example will because it uses more than 5 ports.
