Update HA website page
We need to update the https://about.gitlab.com/high-availability/, especially now that PG HA is GA. I think on general messaging points should be:
- Overview of GitLab HA, it's purpose, and value.
- EEP feature
- How Geo fits into the picture. (DR, local mirror)
- Details on the components:
- Redis & PG HA
- GitLab HA
- BYO HA Storage
Once we update our other tutorials (like the AWS one) we should link them here as well.
