Summary:  

Tracking feature for Support of 3 node compact cluster (with 3 schedulable Masters, and 0 workers); 

Background: 

We introduced 3 node compact clusters for "bare metal" in OCP 4.5 (as GA). This capability is really a cloud agnostic (non cloud provider integration included) way of doing a 3 node compact cluster. Furthermore, it is only available for UPI.  

This feature is to track work of the 3 node compact cluster for all supported infrastructures that OpenShift is supported on using both UPI and IPI. 

Deliverables: 

• Any code changes to installer and other components 
• CI testing 
• QE functional testing 
• Documentation
