MinIO pod isn't able to start as it's missing PodSecurityPolicy

By using examples/minio/componentplan.yaml, statefulset controller failed to create pod and get the error below:

[nkwangleiGIT]

We can add an option to add an existing podsecuritypolicy to role/clusterrole, and let the user configure the name of podsecuritypolicy in values.yaml?
