    Fix error when running k8s cert rotation on c1

    Review https://review.opendev.org/c/starlingx/config/+/884627
    introduced parameter --config /etc/kubernetes/kubeadm.yaml for
    kubeadm certs check-expiration, which generates a better output
    without warnings, that are print when run without.

    File /etc/kubernetes/kubeadm.yaml, however, is not present on
    controller-1 so this is not a good solution. This commit removes the
    usage of the parameter so that the script can work on both environments.

    This script runs as a cron job only on controller nodes.

    PASS: Trigger execution of script kube-cert-rotation.sh on c0, verify
          that it runs without error. Run 'fm alarm-list' and verify no
          'Kubernetes certificates renewal failed are present'
    PASS: Trigger execution of script kube-cert-rotation.sh on c1, verify
          that it runs without error. Run 'fm alarm-list' and verify no
          'Kubernetes certificates renewal failed are present'
