kubernetes: Add boot.sh options to preserve state dir and to set MAC
Not having to redo the kubeadm-init.sh step massively speeds up the test/dev cycle. Having the same MAC (and hence same IP) is useful there too since you don't need to figure out the mac on each boot. Signed-off-by: Ian Campbell <ijc@docker.com>
