Subject: [PATCH] kubernetes: give more resources to worker nodes.

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 54ddde0d4344 but
accidentally reintroduced (by me) in 62aa9248a406, whack it again.
