Support for Google Regional Clusters/PD's
In 1.10, regional PD's are now available which provide a method to have a single PD replicated in multiple AZ's (single region).
This makes Regional Clusters a very attractive solution for running GitLab HA, since our main issue has been reliance on a single gitaly PD for repos. This provides a way for gitaly to seamlessly survive an AZ failure.
We should look into this, an see if there is anything special we need to do to make this work.
