Remove docker health handler from kubelet /healthz

Browse Source 
Docker's health is checked separately from kubelet by the processing monitoring
tool (e.g., supervisord). kubelet should not be killed when docker is down.
This change removes the docker health handler from kubelet's /healthz handler.
