[WIP] Add a values.yaml for disabling persistence
Sometimes it is helpful to disable persistence when testing changes quickly, that way developers are not hampered by waiting on PVCs to bind or flooding a datastore with storage requests. This will disable persistence for the following components:
- postgresql
- redis
- minio
- gitaly
Since this is cribbed from the minimal values for gke, which does not install prometheus, I have left its persistence flag out.
