Expected Behavior

I should be able to create a google_compute_global_forwarding_rule even though my project's default network tier is STANDARD. When it failed, I expected there to be a network_tier attribute (with PREMIUM as the default value) so that it would work.

Actual Behavior

I got the following error message:

│ Error: Error creating GlobalForwardingRule: googleapi: Error 400: STANDARD network tier (the project's default network tier) is not supported: STANDARD network tier is not supported for global forwarding rule., badRequest

And I was not able to set the network_tier manually because this attribute isn't there, so I had to temporarily set the project's default network tier as PREMIUM.

Steps to reproduce

terraform apply

Important Factoids

From what I've seen here in the latest source code version, the attribute network_tier still isn't there: https://github.com/hashicorp/terraform-provider-google/blob/main/google/services/compute/resource_compute_global_forwarding_rule.go
