Goal

An admin today has the ability to set a default CPU model on the cluster via
https://docs.openshift.com/container-platform/4.15/virt/virtual_machines/advanced_vm_management/virt-configuring-default-cpu-model.html

The goal of this epic is to enable the admin to understand 2 things:

1. What CPU models are available on the cluster at what quantity, in order to make a quantity based decision ("what cpus do I have most")
2. What are the most recent CPUs in order to make a qualitative decision ("what is the best cpu") (stretched, only if libvirt is providing this by now)

User Stories

• "As a cluster administrator,
  I Want to run `virtctl cluster cpus` in order to see all CPUs and their quantity,
  so that I can then set one of them as the default on the cluster level."
• "As a cluster administrator,
  I Want to run `virtctl cluster cpus --make-default THE_MODEL`
  so that I can set the CPU model THE_MODEL as the default on the cluster level (virtctl patches kubevirtcr)

Non-Requirements

• List of things not included in this epic, to alleviate any doubt raised during the grooming process.

Notes

• Any additional details or decisions made/needed
