We'll want a static IP address for our GitLab installation
- We should have a static IP such that it's a tad easier to manage DNS
- If the ingress is accidentally removed, we can simply reapply the ingress config with a static IP address
- We already have started this install, so let's take our existing IP, make it static, and make terraform know about it
