58b5b21f0d Don't pass cloud-provider flag to controller-manager
As per documentation, the cloud-provider flag should not be passed to
controller-manager when using cloud-controller. However, the legacy
cloud-related controllers still need to be explicitly disabled to
prevent errors from being logged.

Fixing this also prevents controller-manager from creating the
cloud-controller-manager service account that needed extra RBAC.

31575e407a Add Cluster ID support to k3s stub cloud controller
Resolves warning 2 from #2471.

As per https://github.com/kubernetes/cloud-provider/issues/12 the
ClusterID requirement was never really followed through on, so the
flag is probably going to be removed in the future.

One side-effect of this is that the core k8s cloud-controller-manager
also wants to watch nodes, and needs RBAC to do so.

8c6d3567fe Rename k3s-controller based on the build-time program name
Since we're replacing the k3s rolebindings.yaml in rke2, we should allow
renaming this so that we can use the white-labeled name downstream.

e2089bea18 cli: add --selinux flag to agent/server sub-cmds (#2111)
* cli: add --selinux flag to agent/server sub-cmds

Introduces --selinux flag to affirmatively enable SELinux in containerd.
Deprecates --disable-selinux flag which now defaults to true which
auto-detection of SELinux configuration for containerd is no longer
supported.  Specifying both --selinux and --disable-selinux will result
in an error message encouraging you to pick a side.

* Update pkg/agent/containerd/containerd.go

update log warning message about enabled selinux host but disabled runtime

4808c4e7d5 Listen insecurely on localhost only
Before this change, k3s configured the scheduler and controller's
insecure ports to listen on 0.0.0.0. Those ports include pprof, which
provides a DoS vector at the very least.

These ports are only enabled for componentstatus checks in the first
place, and componentstatus is hardcoded to only do the check on
localhost anyway (see
https://github.com/kubernetes/kubernetes/blob/v1.18.2/pkg/registry/core/rest/storage_core.go#L341-L344),
so there shouldn't be any downside to switching them to listen only on
localhost.

072396f774 Start kube-apiserver in the background
In rke2 everything is a static pod so this causes a chicken and egg situation
in which we need the kubelet running before the kube-apiserver can be
launched.  By starting the apiserver in the background this allows us to
do this odd bootstrapping.

2f5ee914f9 Add supervisor port
In k3s today the kubernetes API and the /v1-k3s API are combined into
one http server.  In rke2 we are running unmodified, non-embedded Kubernetes
and as such it is preferred to run k8s and the /v1-k3s API on different
ports.  The /v1-k3s API port is called the SupervisorPort in the code.

To support this separation of ports a new shim was added on the client in
then pkg/agent/proxy package that will launch two load balancers instead
of just one load balancer.  One load balancer for 6443 and the other
for 9345 (which is the supervisor port).
