Can you update deploy/all.yaml? Or come up with a better process. Currently that file is referenced by the our install guide and the EKS docs. We could add a generation script, or modify both to reference each yaml file in deploy individually, or remove the individual files and only update all.yaml.

To keep it simple, i think we can get rid of individual files in favor of all.yaml. Will follow up in a separate PR if that is ok.
