Feature Overview (aka. Goal Summary)  

Add support to Lsv4 and Lasv4 machine series to be used on OpenShift deployment in Azure

Goals (aka. expected user outcomes)

As a user, I can deploy OpenShift in Azure using Lsv4 and/or Lasv4 machine series so both the Control Plane and Compute Nodes can run on these machine series

Requirements (aka. Acceptance Criteria):

The new machines series that will be available in Azure soon, Lsv4 and Lasv4 can be selected at install time to be used to deploy OpenShift on Azure

Anyone reviewing this Feature needs to know which deployment configurations that the Feature will apply to (or not) once it's been completed.  Describe specific needs (or indicate N/A) for each of the following deployment scenarios. For specific configurations that are out-of-scope for a given release, ensure you provide the OCPSTRAT (for the future to be supported configuration) as well.

Out of Scope

These machines series will be available for OpenShift to be used once they are declared GA by Microsoft

Background

We are getting some requests for upcoming Azure LSv4 instance types.  They will be similar to these in terms of NVME support.  Lsv4 will have NVMe for remote storage as well as local storage. Lasv3 for comparison was SCSI for remote storage and NVMe for local storage. Supposedly, Openshift gets errors when trying to spin up MANA VMs due to the remote storage being NVMe the remote storage NVMe is the big difference between Lsv4/Lsv3.

They want to make use of the Azure Boost instances that utilize the MANA drivers.

Documentation Considerations

Usual documentation to list these machine series as tested 

Interoperability Considerations

This feature will be consumed by ARO later
