Feature Overview

Improve the cluster expansion with the agent workflow added in OpenShift 4.16 (TP) and OpenShift 4.17 (GA) with:

• Caching RHCOS image for faster node addition, i.e. no extraction of image every time)
• Add a single node with just one command, no need to write config files describing node
• Support creating PXE artifacts 

Goals

Improve the user experience and functionality of the commands to add nodes to clusters using the image creation functionality.
