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.

Using the node external IP address for all CNI traffic is a breaking change from previous versions; we should make it an opt-in for distributed clusters instead of default behavior.

* Use INVOCATION_ID to detect execution under systemd, since as of a9b5a1933f NOTIFY_SOCKET is now cleared by the server code.
* Set the unit type to notify by default for both server and agent, which is what Rancher-managed installs have done for a while.

* Switch default systemd notification to server
* Add 1 sec delay to allow etcd to write to disk

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.

Watching pods appears to be the most reliable way to ensure that the
proxy routes and authorizes connections.

Allow the flannel backend to be specified as
backend=option=val,option2=val2 to select a given backend with extra options.
In particular this adds the following options to wireguard-native
backend:
* Mode - flannel wireguard tunnel mode
* PersistentKeepaliveInterval- wireguard persistent keepalive interval

Before this change, kube-router was always assuming that IPv4 is
enabled, which is not the case in IPv6-only clusters. To enable network
policies in IPv6-only, we need to explicitly let kube-router know when
to disable IPv4.
