Yibo Zhuang f87b57bbc5 Begin work on adding DiskImageKit to tart (#1303)
This is first of several changes to add support for the new
DiskImageKit ASIF layers to tart VM images.

This change is focused on laying down the OCI media type for
ASIF layers, content addressable store structure, as well
as the VMDirectory structure for supporting layers.

Add DiskImageStack type to model VM image using DiskImage APIs.

Tart is a virtualization toolset to build, run and manage macOS and Linux virtual machines (VMs) on Apple Silicon. Built by CI engineers for your automation needs. Here are some highlights of Tart:

  • Tart uses Apple's own Virtualization.Framework for near-native performance.
  • Push/Pull virtual machines from any OCI-compatible container registry.
  • Use Tart Packer Plugin to automate VM creation.
  • Easily integrates with any CI system.

Many companies are using Tart in their internal setups. Here are just a few of them:

Note: If your company or project is using Tart please consider sharing with the community.
