Motivation: Allow users to change the default RBAC resources (ServiceAccount, ClusterRole, ClusterRoleBinding, Role and RoleBinding) without having Mizu delete them every run.
Adds app.kubernetes.io/created-by and app.kubernetes.io/managed-by labels to all resources.
The value of app.kubernetes.io/created-by is either mizu-cli or mizu-agent.
The value of app.kubernetes.io/managed-by is mizu.
When Mizu cleans resources (ctrl-c in tap cmd or mizu clean cmd) it removes all RBAC resources that have managed-by=mizu, and only those.
A user may have a ClusterRole named mizu-clusterrole. If it doesn't have the label app.kubernetes.io/managed-by=mizu, then Mizu won't overwrite it and won't delete it.
Other resources (deployments, services etc.) are always removed, regardless of their labels.
