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.

The sock-shop demo[0] requires around 5G of images on a worker node and 3G of
RAM (if there is only one worker node and therefore everything runs on that
node).
Since the master is more than happy with the 4G disk and 1G RAM it is given
today split the settings into master and node specific and bump only the
latter.
KUBE_PORT_BASE is unused and was already removed in 54ddde0d43 but
accidentally reintroduced (by me) in 62aa9248a4, whack it again.

Because Kubernetes is 1.5GB, ISO makes sense as the files do not
take up memory, so you can boot a 1GB machine rather than a 4GB one.

Remove `-publish` (which is currently Linux/QEMU specific) and replace with a
generic $KUBE_RUN_ARGS envvar. Usage:
KUBE_RUN_ARGS="-publish 2222:22" ./boot.sh
KUBE_PORT_BASE is thus obsolete and removed.

Port base is configurable (via $KUBE_PORT_BASE envvar). Master uses this and
nodes use subsequent ports.
Check that the node number is numeric so we can add them to things, but avoid
worker node 0 since the port will clash with master.
