Fix URL pruning when joining an etcd member (#3832) 
* Fix URL pruning when joining an etcd member

Problem:
Existing member clientURLs were checked if they contain the joining
node's IP. In some edge cases this would prune valid URLs when the
joining IP is a substring match of the only existing member's IP.
Because of this, it was impossible to e.g. join 10.0.0.2 to an existing
node that has an IP of 10.0.0.2X or 10.0.0.2XX:

level=fatal msg="starting kubernetes: preparing server: start managed database:
joining etcd cluster: etcdclient: no available endpoints"

Solution:
Fixed by properly parsing the URLs and comparing the IPs for equality
instead of substring match.

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
