Adds instructions to deploy locally without Cloud Build.

[amandakarina]

TODOs:

• Add empty commit in each local repo
• Add env promotion aka.: git merge from dev to nonprod to prod
• Follow the same tone/text of instructions in all steps.
• Remove BU2 copy instructions until fix
• Add step 5-app-infra instructions
• Remove cloud build from 4-projects

LGTM.

@amandakarina how did you run the 4-projects step?

in my case it was not working because in cb.tf at bootstrap, the gcs_projects bucket is created, and we discard the file by renaming it to cb.tf.example:

module "gcp_projects_state_bucket" {
  source  = "terraform-google-modules/cloud-storage/google//modules/simple_bucket"
  version = "~> 6.0"

  name          = "${var.bucket_prefix}-${module.seed_bootstrap.seed_project_id}-gcp-projects-tfstate"
  project_id    = module.seed_bootstrap.seed_project_id
  location      = var.default_region
  force_destroy = var.bucket_force_destroy

  encryption = {
    default_kms_key_name = local.state_bucket_kms_key
  }

  depends_on = [module.seed_bootstrap.gcs_bucket_tfstate]
}

I was able to run by creating the module above in a separate file, have you done something different?

The projects state bucket creation was moved from cb.tf tot main.tf.

After testing your PR, here are some key points:

• at 0-bootstrap, in sa.tf the field local.cicd_project_id also needed to be commented out to run terraform plan/apply. Besides that, 1-org to 4-projects is running smoothly
• I'm gonna make a PR to your branch addressing the local.cicd_project_id issue
