Allows nodes to join the cluster during a webhook outage. This also
enhances auditability by creating Kubernetes events for the deferred
verification.

Only actual admin actions should use the admin kubeconfig; everything done by the supervisor/deploy/helm controllers will now use a distinct account for audit purposes.

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.

Having separate tokens for server and agent nodes is a nice feature.
However, passing server's plain `K3S_AGENT_TOKEN` value
to `k3s agent --token` without CA hash is insecure when CA is
self-signed, and k3s warns about it in the logs:
```
Cluster CA certificate is not trusted by the host CA bundle, but the token does not include a CA hash.
Use the full token from the server's node-token file to enable Cluster CA validation.
```
Okay so I need CA hash but where should I get it?
This commit attempts to fix this issue by saving agent token value to
`agent-token` file with CA hash appended.

This parameter controls which namespace the klipper-lb pods will be create.
It defaults to kube-system so that k3s does not by default create a new
namespace. It can be changed if users wish to isolate the pods and apply
some policy to them.

This controller only needs to run when using managed etcd, so move it in
with the rest of the etcd stuff. This change also modifies the
controller to only watch the Kubernetes service endpoint, instead of
watching all endpoints in the entire cluster.
Fixes an error message revealed by use of a newer grpc client in
Kubernetes 1.24, which logs an error when the Put to etcd failed because
kine doesn't support the etcd Put operation. The controller shouldn't
have been running without etcd in the first place.

the server's built-in helm controller.
Problem:
Testing installation and uninstallation of the Helm Controller on k3s is
not possible if the Helm Controller is baked into the k3s server.
Solution:
The Helm Controller can optionally be disabled, which will allow users
to manage its installation manually.

K3s upgrade via watch over file change of static file and manifest
and triggers helm-controller for change. It seems reasonable to
only allow upgrade traefik v1->v2 when there is no existing custom
traefik HelmChartConfig in the cluster to avoid any
incompatibility.
Here also separate the CRDs and put them into a different chart
to support CRD upgrade.
