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

Euan Kemp 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.

Darren Shepherd 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.

Darren Shepherd 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).

Darren Shepherd afd6f6d7e7 Encapsulate execution logic 
This moves all the calls to cobra root commands to one package

or external.

Kubernetes componentstatus check is hardcoded to 10252 and 10251
so we should never change these ports.  If you do componentstatus
will return error.
