Brad Davidson 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.

Brad Davidson fc1c100ffd Remove legacy bidirectional datastore sync code
Since #4438 removed 2-way sync and treats any changed+newer files on disk as an error, we no longer need to determine if files are newer on disk/db or if there is a conflicting mix of both. Any changed+newer file is an error, unless we're doing a cluster reset in which case everything is unconditionally replaced.

Brad Davidson 8ad7d141e8 Close etcd clients to avoid leaking GRPC connections
If you don't explicitly close the etcd client when you're done with it,
the GRPC connection hangs around in the background. Normally this is
harmelss, but in the case of the temporary etcd we start up on 2399 to
reconcile bootstrap data, the client will start logging errors
afterwards when the server goes away.

Always use static ports for client load-balancers (#3026)
* Always use static ports for the load-balancers

This fixes an issue where RKE2 kube-proxy daemonset pods were failing to
communicate with the apiserver when RKE2 was restarted because the
load-balancer used a different port every time it started up.

This also changes the apiserver load-balancer port to be 1 below the
supervisor port instead of 1 above it. This makes the apiserver port
consistent at 6443 across servers and agents on RKE2.

Additional fixes below were required to successfully test and use this change
on etcd-only nodes.

* Actually add lb-server-port flag to CLI
* Fix nil pointer when starting server with --disable-etcd but no --server
* Don't try to use full URI as initial load-balancer endpoint
* Fix etcd load-balancer pool updates
* Update dynamiclistener to fix cert updates on etcd-only nodes
* Handle recursive initial server URL in load balancer
* Don't run the deploy controller on etcd-only nodes

Brad Davidson a3bbd58f37 Fix managed etcd cold startup deadlock issue #2249
We should ignore --token and --server if the managed database is initialized,
just like we ignore --cluster-init. If the user wants to join a new
cluster, or rejoin a cluster after --cluster-reset, they need to delete
the database. This a cleaner way to prevent deadlocking on quorum loss,
and removes the requirement that the target of the --server argument
must be online before already joined nodes can start.
