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.

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.

6b5b69378f Add embedded etcd support 
This is replaces dqlite with etcd.  The each same UX of dqlite is
followed so there is no change to the CLI args for this.

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).

77703b90ff Don't ever change 10252/10251 ports 
Kubernetes componentstatus check is hardcoded to 10252 and 10251
so we should never change these ports.  If you do componentstatus
will return error.
