Reuse the existing etcd library code to start up the temporary etcd
server for bootstrap reconcile. This allows us to do proper
health-checking of the datastore on startup, including handling of
alarms.

Several types contained redundant references to ControlRuntime data. Switch to consistently accessing this via config.Runtime instead.

(cherry picked from commit 2989b8b2c5)
If you don't explicitly close the etcd client when you're done with it,
the GRPC connection hangs around in the background. Normally this is
harmelss, but in the case of the temporary etcd we start up on 2399 to
reconcile bootstrap data, the client will start logging errors
afterwards when the server goes away.

* 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
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.
