Bug Description

Brief Description
-----------------
When we originally implemented the deployment of the kubernetes HA cluster using kubeadm, the instructions for the second master node were to copy certificate files from the first master node and then run the "kubeadm init" command with the same yaml file used on the first master node. However, in a subsequent release, the instructions (see https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/high-availability) changed to use the "kubeadm join" with a --control-plane option instead. This approach is simpler and the approach we are currently using is no longer supported (although it still seems to be working).

Severity
--------
Minor - although I expect the method we are using will no longer work at some point

Steps to Reproduce
------------------
Install a system with two controllers

Expected Behavior
------------------
We should be using the supported kubadm instructions.

Actual Behavior
----------------
We are following obsolete instructions.

Reproducibility
---------------
Reproducible

System Configuration
--------------------
Any system with two controller hosts

Branch/Pull Time/Commit
-----------------------

Last Pass
---------

Timestamp/Logs
--------------

Marking as stx.3.0 / medium priority - prefer to align on the supported method for the stx.3.0 release.
