Nextcloud in K8s: MVP

This is the minumum needed to run a multinode customer in kubernetes.
Each customer will run in their own namespace with a nextcloud
container and a redis container. There is a proxysql cluster running in
its own namespace, used by all customer.

This is a monorepo that uses kustomize to allow using this repo for both
prod and test (and other things we can think of in the future).
