Etcd server version upgrades #98

Closed adamhosier closed 4 years ago

adamhosier commented 4 years ago

We must be able to deploy updates to the etcd version running in clusters.

AC:

A version field is added to the cluster spec to allow users to specify the etcd version to use
The cluster controller is responsible for upgrading peer resources to specify the required version
The peer controller is responsible for rolling the etcd pod to the upgraded version
No cluster-wide downtime
