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.

b550e1183a Remove control-plane egress context and fix agent mode. 
The control-plane context handles requests outside the cluster and
should not be sent to the proxy.

In agent mode, we don't watch pods and just direct-dial any request for
a non-node address, which is the original behavior.
