What happened: controller-manager panic when field insecure-skip-tls-verify of kubeconfig is ture
What you expected to happen:
How to reproduce it (as minimally and precisely as possible):
apiVersion: v1 clusters: - cluster: insecure-skip-tls-verify: true # Set this field to true.
Anything else we need to know?:
