[RFE] Enhance w/ IaC for Kargo on Kargo nested kubevirt platform development

[usrbinkat]

Problem:

Currently, platform development cycle velocity is capped at the speed of bare metal iteration which is significantly slower and more cumbersome than developing on virtual infrastructure.

Recommend:

Write the official virtualized platform developer workflow IaC and docs to deliver a low effort nested platform in platform development environment for Kargo contributors.
