virtualisation: implement kubevirt config
virtualisation: implement kubevirt config

KubeVirt[1] allows for VMs to be run and managed as pods inside of
Kubernetes clusters. Information about the guests can be exposed through
qemu-guest-agent[2] as well as startup scripts can be injected through
cloud-init[3].

This config has been duplicated and modified from the `cloudstack`
config/script.

To test this out, deploy KubeVirt locally with KinD[4], build the disk
image, then package it into a container image (or upload to CDI[5]) and
provision a VirtualMachine.
