Support for custom labels on ClusterRole resources

[odise]

I would like to add some dedicated labels on the ClusterRole resources deployed with the vertical-pod-autoscaler chart.

Here is an example:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  labels:
    rbac.authorization.k8s.io/aggregate-to-admin: "true"
    rbac.authorization.k8s.io/aggregate-to-edit: "true"
  name: vertical-pod-autoscaler-vertical-pod-autoscaler-recommender
rules:
  ...

If you want me to provide a PR, don't hesitate to give me a wink. Thanks a bunch.

I'm not fan of doing this because the cluster roles in the chart are intended for the VPA components not for people or other applications.

If you want to give access to VPA custom ressources, you can use the extraDeploy value to create a new cluster role that will have the labels you want.
