Brad Davidson c44d33d29b Fix race condition in tunnel server startup
Several places in the code used a 5-second retry loop to wait on
Runtime.Core to be set. This caused a race condition where OnChange
handlers could be added after the Wrangler shared informers were already
started. When this happened, the handlers were never called because the
shared informers they relied upon were not started.

Fix that by requiring anything that waits on Runtime.Core to run from a
cluster controller startup hook that is guaranteed to be called before
the shared informers are started, instead of just firing it off in a
goroutine that retries until it is set.

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.

* Bump etcd to v3.5.4-k3s1
* Fix issue with datastore corruption on cluster-reset
* Disable unnecessary components during cluster reset

Disable control-plane components and the tunnel setup during
cluster-reset, even when not doing a restore. This reduces the amount of
log clutter during cluster reset/restore, making any errors encountered
more obvious.

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.
