The latest major version of terraform (v0.13) [has hit GA](https://www.terraform.io/upgrade-guides/0-13.html), and we should start planning to upgrade sooner rather than later, to avoid unnecessary tech debt. Luckily in this case, it doesn't *appear* that we'll have too many significant hurdles when upgrading (it certainly appears to be much more straightforward than the upgrade from `0.11` to `0.12`). This is a separate issue from https://gitlab.com/gitlab-com/gl-infra/infrastructure/-/issues/11224 but it would probably be a good idea to do them at the same time. These are the issues to push [the changes](https://ops.gitlab.net/gitlab-com/services-base/-/merge_requests/165) to the Auto-Devops environments: - [x] [services-staging](https://ops.gitlab.net/gitlab-com/services-base/-/merge_requests/166) - [x] [services-prod](https://ops.gitlab.net/gitlab-com/services-base/-/merge_requests/167) - [x] [license-stg](https://ops.gitlab.net/gitlab-com/services-base/-/merge_requests/168) - [x] [license-prd](https://ops.gitlab.net/gitlab-com/services-base/-/merge_requests/169) - [x] [gs-staging](https://ops.gitlab.net/gitlab-com/services-base/-/merge_requests/170) - [x] [gs-production](https://ops.gitlab.net/gitlab-com/services-base/-/merge_requests/171)
