The help for delete claims that the default namespace is default but it still only does a partial cleanup with the -n flag. E.g. the operator pod is still running.

-bash-4.2$ kubectl minio delete -h

'delete' command delete MinIO Operator deployment along with all the tenants.

Usage:
  minio delete [flags]

Examples:
  kubectl minio delete

Flags:
  -h, --help               help for delete
  -n, --namespace string   namespace scope for this request (default "default")
-bash-4.2$ kubectl minio delete -n minio-operator
Are you sure you want to delete ALL the MinIO Tenants and MinIO Operator? [Y/N]: y

@jhoblitt thanks for reporting the issue, I've sent one pr to fix some issues. ^

I haven't checked all the resources yet but I can confirm that at least the clusterrolebinding for the console is now being cleaned up. Thank you!
