Problem:
Configuring qos-class features in containerd requres a custom containerd configuration template.
Solution:
Look for configuration files in default locations and configure containerd to use them if they exist.

Enable the feature-gate for both kubelet and cloud-controller-manager. Enabling it on only one side breaks RKE2, where feature-gates are not shared due to running in different processes.

* Add --image-service-endpoint flag
Problem:
External container runtime can be set but image service endpoint is unchanged
and also is not exposed as a flag. This is useful for using containerd
snapshotters outside of the ones that have built-in support like
stargz-snapshotter.
Solution:
Add a flag --image-service-endpoint and also default image service endpoint to
container runtime endpoint if set.

Problem:
When support for etcd was added in 3957142, generation of certificates and keys for etcd was not gated behind use of managed etcd.
Keys are generated and distributed across servers even if managed etcd is not enabled.
Solution:
Allow generation of certificates and keys only if managed etc is enabled. Check config.DisableETCD flag.

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.

Turns out etcd-only nodes were never running **any** of the controllers,
so allowing multiple controllers didn't really fix things.

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.
