vagrant: 'kubeadm init --skip-preflight-checks' is deprecated

New versions of kubeadm do not have --skip-preflight-checks anymore. It seems to have been replaced by --ignore-preflight-errors=all. Before running 'kubeadm init', check if the help text lists the --skip-preflight-checks option. If it does, then it needs to be used, otherwise use --ignore-preflight-errors=all by default.
