* Refactor agent supervisor listener startup and authn/authz to use upstream
auth delegators to perform for SubjectAccessReview for access to
metrics.
* Convert spegel and pprof handlers over to new structure.
* Promote bind-address to agent flag to allow setting supervisor bind
address for both agent and server.
* Promote enable-pprof to agent flag to allow profiling agents. Access
to the pprof endpoint now requires client cert auth, similar to the
spegel registry api endpoint.
* Add prometheus metrics handler.

Render cri registry mirrors.x.endpoints and configs.x.tls into config_path; keep
using mirrors.x.rewrites and configs.x.auth those do not yet have an
equivalent in the new format.
The new config file format allows disabling containerd's fallback to the
default endpoint when using mirror endpoints; a new CLI flag is added to
control that behavior.
This also re-shares some code that was unnecessarily split into parallel
implementations for linux/windows versions. There is probably more work
to be done on this front but it's a good start.

* Add --image-service-endpoint flag
Problem:
External container runtime can be set but image service endpoint is unchanged
and also is not exposed as a flag. This is useful for using containerd
snapshotters outside of the ones that have built-in support like
stargz-snapshotter.
Solution:
Add a flag --image-service-endpoint and also default image service endpoint to
container runtime endpoint if set.

* Always use static ports for the load-balancers
This fixes an issue where RKE2 kube-proxy daemonset pods were failing to
communicate with the apiserver when RKE2 was restarted because the
load-balancer used a different port every time it started up.
This also changes the apiserver load-balancer port to be 1 below the
supervisor port instead of 1 above it. This makes the apiserver port
consistent at 6443 across servers and agents on RKE2.
Additional fixes below were required to successfully test and use this change
on etcd-only nodes.
* Actually add lb-server-port flag to CLI
* Fix nil pointer when starting server with --disable-etcd but no --server
* Don't try to use full URI as initial load-balancer endpoint
* Fix etcd load-balancer pool updates
* Update dynamiclistener to fix cert updates on etcd-only nodes
* Handle recursive initial server URL in load balancer
* Don't run the deploy controller on etcd-only nodes
Adds support for retagging images to appear to have been sourced from
one or more additional registries as they are imported from the tarball.
This is intended to support RKE2 use cases with system-default-registry
where the images need to appear to have been pulled from a registry
other than docker.io.

* 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

Values passed in via the server/agent `--node-label` flag are treated as mutable. They are passed through to the kubelet just as before but after the kubelet comes up they are applied again. This allows for passing labels a k3s start-time that may be necessary for scheduling but may change from boot to boot, e.g. `k3os.io/version` after an upgrade.
Tested locallon on my amd64 workstation with the docker container.
Addresses #1119.
