 In order to achieve the joining flow using the token as the only piece of validation information, a
  ConfigMap with some data needed for validation of the master's identity is exposed publicly by
 default. While there is no private data in this ConfigMap, some users might wish to turn
 it off regardless. Doing so will disable the ability to use the `--discovery-token` flag of the
 `kubeadm join` flow. Here are the steps to do so:
