ClusterRoles and ClusterRoleBindings wrongly contain the namespace in the metadata section

[Raffo]

What happened:

Some ClusterRoleBindings and ClusterRoles contain a namespace in the metadata section. This is "invalid" as the resources are not namespaced as mentioned in the documentation https://kubernetes.io/docs/reference/access-authn-authz/rbac/#clusterrole-example.

What you expected to happen:

I would expect the YAML for ClusterRoles and ClusterRoleBindings to not contain the metadata.namespace field.

How to reproduce it:

Just a visual inspection of https://github.com/kubernetes-sigs/azuredisk-csi-driver/blob/master/charts/latest/azuredisk-csi-driver/templates/rbac-csi-snapshot-controller.yaml#L62 and other files.

Anything else we need to know?:

I would love to understand what is the process to address that. Should I change the manifests in latest? Would a fix be backported? Happy to help once I understand how this is supposed to work.

Environment:

• CSI Driver version: v1.1.1
• Kubernetes version (use kubectl version): 1.19
• OS (e.g. from /etc/os-release): default AKS node OS

This is the same problem as kubernetes-sigs/azuredisk-csi-driver#819
