Brad Davidson 8ace8975d2 Don't start up multiple apiserver load balancers
get() is called in a loop until client configuration is successfully
retrieved. Each iteration will try to configure the apiserver proxy,
which will in turn create a new load balancer. Skip creating a new
load balancer if we already have one.

Brad Davidson 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

Initial Logging Output Update (#2246)
This attempts to update logging statements to make them consistent
through out the code base. It also adds additional context to messages
where possible, simplifies messages, and updates level where necessary.

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).
