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.

ca9c9c2e1e Adding support for TLS MinVersion and CipherSuites 
This will watch for the following kube-apiserver-arg variables and apply
them to the k3s kube-apiserver https listener.

  --kube-apiserver-arg=tls-cipher-suites=XXXXXXX
  --kube-apiserver-arg=tls-min-version=XXXXXXX

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).

afd6f6d7e7 Encapsulate execution logic 
This moves all the calls to cobra root commands to one package
so that we can change the behavior of running components as embedded
or external.

fa03a0df3c Run kubelet with containerd flag 
The containerd flag was accidentally added to kubelet and is
deprecated, but needed for cadvisor to properly connect with
the k3s containerd socket, so adding for now.

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.
