What type of PR is this?

/kind cleanup

What this PR does / why we need it:

After upgrading to newer Kubernetes(v1.17 at least), kubectl command shows the following warning message:

  WARNING: Kubernetes configuration file is group-readable.
  This is insecure. Location: /home/foo/.kube/config

The kubeconfig was copied from {{ artifacts_dir }}/admin.conf with kubeconfig_localhost feature. It is better to set valid file mode at getting it on Kubespray.

Does this PR introduce a user-facing change?:
