Add terraform downgrade requirements to 1.3.0 to avoid state file errors in cloud build - as of 20230312 GCP cloud shell is at terraform 1.7.4 - downgrade or use a local shell

[obriensystems]

TL;DR

Update: should have followed the warning around 1.3.0 in
https://github.com/terraform-google-modules/terraform-example-foundation/pull/831/files
https://github.com/terraform-google-modules/terraform-example-foundation/blob/master/0-bootstrap/README.md#prerequisites

Note: Make sure that you use version 1.3.0 of Terraform throughout this series. Otherwise, you might experience Terraform state snapshot lock errors.

The validation script needs to be updated
https://github.com/terraform-google-modules/terraform-example-foundation/blob/master/scripts/validate-requirements.sh#L94

TF_VERSION="1.3.0"
...
        TERRAFORM_CURRENT_VERSION=$(terraform version -json | jq -r .terraform_version)
        if [ "$(compare_version "$TERRAFORM_CURRENT_VERSION" "$TF_VERSION")" -gt 1 ]; then

## test this change first (locally in just a script unit test or in a new-org deploy)

Note we can go to 1.3.7 - on a minor version but 1.4+ is untested

1-org continued - terraform apply with terraform 1.3 on bootstrap as well as cloud build

• added dns/users and hub-spoke enablement to envs/shared/terraform.tfvars
• run plan
• ok
