Add custom tags

[fmunteanu]

At Expedia we tag resources with specific tags related to project, etc. If these tags are not present, resources will be automatically deleted. Therefore, I implemented the missing tags into terraform-terraform-label modules.

I also added a specific version for the terraform-terraform-label source. With the cluster in production, using master will definitely introduce a risk factor, as mentioned into their documentation. Unfortunately, we cannot use variables into source.

From their documentation:

IMPORTANT: The master branch is used in source just as an example. In your code, do not pin to master because there may be breaking changes between releases. Instead pin to the release tag (e.g. ?ref=tags/x.y.z) of one of our latest releases.

Hi @fmunteanu

Would you mind including an example of use in the example folder?

Thanks!

Good morning @edbizarro, let me know if is satisfactory. This is an example, while planning:

  # module.airflow_cluster.module.sg_airflow.aws_security_group.this_name_prefix[0] will be created
  + resource "aws_security_group" "this_name_prefix" {
      + arn                    = (known after apply)
      + description            = "Security group for floren-dev-airflow machines"
      + egress                 = (known after apply)
      + id                     = (known after apply)
      + ingress                = (known after apply)
      + name                   = (known after apply)
      + name_prefix            = "floren-dev-airflow-sg-"
      + owner_id               = (known after apply)
      + revoke_rules_on_delete = false
      + tags                   = {
          + "Name"      = "floren-dev-airflow-sg"
          + "Namespace" = "floren"
          + "Role"      = "airflow-infrastructure"
          + "Stage"     = "dev"
          + "Team"      = "AI Labs"
        }
      + vpc_id                 = "vpc-08269f58d24108b45"
    }
