When using ScrapeConfig, prometheus cannot get Node information from KubeAPI due to:

ts=2023-10-07T10:28:44.996Z caller=klog.go:116 level=error component=k8s_client_runtime func=ErrorDepth msg="pkg/mod/k8s.io/[email protected]/tools/cache/reflector.go:231: Failed to watch *v1.Node: failed to list *v1.Node: nodes is forbidden: User \"system:serviceaccount:monitoring:prometheus-k8s\" cannot list resource \"nodes\" in API group \"\" at the cluster scope"

This PR is an attempt to resolve this problem.
