Nutanix AOS: Support IPI deployment

Goal: 

As an administrator, I would like to deploy OpenShift 4 on Nutanix AOS leveraging best-practices, installer provisioned infrastructure.

Problem:

Customers would like to be able to easily and quickly deploy OpenShift 4 on other cloud providers rather than being locked into a select few.

Why is this important: 

• This will enable more customers to make the move to OCP 4 by providing deployment support on other popular cloud providers.
• IPI deployment provides a simplified, best-practices OpenShift 4 deployment for customers by leveraging installer provisioned infrastructure objects and nodes enabling faster cluster bring-up time and significantly configurations errors.
• Automated installation process provides the framework for integrating into our CI system.

Dependencies (internal and external):

• RHCOS support + image publishing pipeline
• Machine API
• Image Registry Operator
• Ingress
• Kube Controller Manager
• Cloud Credential Operator

Prioritized epics + deliverables (in scope / not in scope):

• Terraform infrastructure config work
• Support for Nutanix AOS Storage
• OpenShift CI system running on Nutanix AOS infrastructure

Estimate (XS, S, M, L, XL, XXL): 

Previous Work:

• Agnostic installer on Nutanix AOS
