[machine]:windows node setup

[bobsira]

To test this PR follow the steps below

Prerequisites (local machine)

• Local clones of:

1. minikube-machine with the branch for this PR
2. minikube with the branch for this PR

• Optional: windows-node-image-builder repo if you want to build a custom VHD:

1) Prepare local modules (temporary local replace)

Open go.mod in your local minikube repo and temporarily replace the github.com/docker/machine module with your local minikube-machine path.

Before (example upstream replacement)
github.com/docker/machine => github.com/minikube-machine/machine v0.0.0-20240815173309-ffb6b643c381

Temporary local replace( use a Windows absolute path)

- github.com/docker/machine => github.com/minikube-machine/machine v0.0.0-20240815173309-ffb6b643c381
+ github.com/docker/machine => c:/dev/mini-machine/machine

Important: This replace is only for local testing. Remove or revert it before committing/pushing.

2) Build minikube

From the minikube repo root build with make (repo uses make target)

# execute this in git bash 
make

You should now have minikube.exe in the repo out directory

3) Start a hybrid cluster (elevated PowerShell)

Start using the default (built-in) VHD

.\minikube.exe start --kubernetes-version=v1.33.0 -n 2 --node-os='[linux,windows]'

Start using a custom VHD (remote or local)

--windows-vhd-url accepts remote URLs or local absolute paths:

Remote
.\minikube.exe start --kubernetes-version=v1.32.3 -n 2 --node-os='[linux,windows]' --windows-vhd-url='https://<your-storage>/hybrid-minikube-windows-server.vhdx'
Local path
.\minikube.exe start --kubernetes-version=v1.32.3 -n 2 --node-os='[linux,windows]' --windows-vhd-url='C:\vhd\hybrid-minikube-windows-server.vhdx'

4) What to expect

• minikube start provisions a Linux control plane VM and a Windows worker VM.
• VM provisioned from a prebuilt VHD
• kubectl get nodes -o wide should show two nodes with OS labels: one linux, one windows.

Setting up the cluster

Verify your cluster

It'd be nice if the ConfigGuest type had a "IsWindows()" method that we reuse throughout this change. I know it's just a comparison against a string, but this type of comparison changes over time.

This seems like a useful logging message we're removing. Could even enhance it a bit with info about the VM we're starting.

Can you please open a PR against minikube instead, if you still want to continue with this?
