This should give us more detail on how long dials take before failing, so that we can perhaps better tune the retry loop in the future.

We shouldn't be replacing the configured server address on agents. Doing
so breaks the agent's ability to fall back to the fixed registration
endpoint when all servers are down, since we replaced it with the first
discovered apiserver address. The fixed registration endpoint will be
restored as default when the service is restarted, but this is not the
correct behavior. This should have only been done on etcd-only nodes
that start up using their local supervisor, but need to switch to a
control-plane node as soon as one is available.

If proxy.SetAPIServerPort was called multiple times, all calls after the
first one would cause the apiserver address to be set to the default
server address, bypassing the local load-balancer. This was most likely
to occur on RKE2, where the supervisor may be up for a period of time
before it is ready to manage node password secrets, causing the agent
to retry.

It is concievable that users might take more than 60 seconds to deploy their own cloud-provider. Instead of exiting, we should wait forever, but with more logging to indicate what's being waited on.

* 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.

* Adds support for health-checking loadbalancer servers. If a
health-check fails when dialing, all existing connections to the
server will be closed.
* Wires up a remotedialer tunnel connectivity check as the health check
for supervisor/apiserver connections.
* Wires up a simple ping request to the supervisor port as the health
check for etcd connections.

CRI and containerd APIs disagree about the registry names - CRI supports
index.docker.io as an alias for docker.io, while containerd does not.
Use the actual stored RepoTag to determine what image to ask containerd for.
