Support for non-Linux local test environments

[detiber]

Currently the only way to test locally with VMs is to use the Tinkerbell sandbox setup with Vagrant/libvirt on LInux.

The Tinkerbell sandbox also supports Vagrant/Virtualbox, which would provide a more cross-platform local test environment, but due to the networking configuration, does not work with streaming the sigs.k8s.io/image-builder based images from ghcr.io, and the resulting images would fail due to networking configuration even if they were written properly.

We need to either have a way for users to consume the published image-builder built images on Vagrant/Virtualbox or have another way(s) of running a local test environment using Windows and Mac.

Expected Behaviour

Mac/Windows users to have a way to run a local test environment using VMs

Current Behaviour

The only way to run a local test environment on VMs today is on Linux using Vagrant/Libvirt

Possible Solutions

• Enable support for Tinkerbell sandbox Vagrant/Virtualbox environments either by updating hook and sigs.k8s.io/image-builder to support the Virtualbox networking configuration by default
• Possibly support the Virtualbox networking environment using a combination of:
  • Configuring the Tinkerbell hardware networking configuration differently to better support the VirtualBox networking config
  • Ensuring that hook properly initializes all defined networking devices listed in the hardware configuration
  • Have a cluster template that can be used with Vagrant/Virtualbox to properly configure the networking devices defined in Hardware and not just the first device.
    • This may also require some changes to the cloud-init configuration injected into the written image by the CAPT-generated workflow template, longer term if this is needed it should be addressed via proper cloud-init support for Tinkerbell
• Provide an alternative setup for local VMs on Windows/Mac (preferably adding support to tinkerbell/sandbox instead of a one-off setup for this repo).
