[feat:] Adding init command

[alfsuse]

Adding an "init" command to check and deploy the K3s or Kind cluster to use with k3ai

k3ai-cli init

Should drive you through an interactive UI that :

1. Check if KUBECONFIG is configure
2. Check if K3s is installed
3. Offer a selection of local cluster installations (k3s, kind,...k0s is not implemented)
4. Based on selection check if you are on Windows or Linux and based on result install (WSL support)

@Gsantomaggio I've added the macOS support for Kind but since I do not have a mac could you please check if everything works as expected?
