c0d129003b Handle loadbalancer port in TIME_WAIT 
If the port wanted by the client load balancer is in TIME_WAIT, startup
will fail. Set SO_REUSEPORT so that it can be listened on again
immediately.

The configurable Listen call wants a context, so plumb that through as
well.

Always use static ports for client load-balancers (#3026) 
* 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

a3bbd58f37 Fix managed etcd cold startup deadlock issue #2249 
We should ignore --token and --server if the managed database is initialized,
just like we ignore --cluster-init. If the user wants to join a new
cluster, or rejoin a cluster after --cluster-reset, they need to delete
the database. This a cleaner way to prevent deadlocking on quorum loss,
and removes the requirement that the target of the --server argument
must be online before already joined nodes can start.

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).
