992e64993d Add support for kubeadm token and client certificate auth
Allow bootstrapping with kubeadm bootstrap token strings or existing
Kubelet certs. This allows agents to join the cluster using kubeadm
bootstrap tokens, as created with the `k3s token create` command.

When the token expires or is deleted, agents can successfully restart by
authenticating with their kubelet certificate via node authentication.
If the token is gone and the node is deleted from the cluster, node auth
will fail and they will be prevented from rejoining the cluster until
provided with a valid token.

Servers still must be bootstrapped with the static cluster token, as
they will need to know it to decrypt the bootstrap data.

This command must be run on a server while the service is running. After this command completes, all the servers in the cluster should be restarted to load the new CA files.
