Subject: [PATCH] feat: Make it possible to customize k8s resources

Currently there is no way for plugins to customize Kubernetes resources
defined in Tutor deployment manifests.
This change makes that possible by taking advantage of the strategic
merge patching mechanism in `kustomization.yml`.
Any resource definition in a `k8s-override` patch in a plugin will
override the resource defined by Tutor, provided that their names match.
