We now explicitly generate certs before starting the cluster.

Set the k8s version strings during build.

Fix test.sh to run on mac.

The find command errors on Mac. This uses "go list", which should
be easier to maintain going forward.

Also switch to one "go test" execution with many paths. This lets
go test parallelize more effectively, and cuts the runtime down
from 2.5m to 1.5m on my workstation.

Fix bug in start.

We have to call save after start, because the IP/port might change.

Fix dependency tracking in the Makefile

Added Run Requirements section to README.md

Enable SecurityContext features.

Setup kubeconfig on cluster start

Add ethtool to the built image.

Make .gitignore paths absolute.

Integration test to verify cluster components are healthy.

Make the ISO url configurable for testing new ISO builds.

This statically compiles socat so it actually works in our iso.

Fix make clean.

Update kubernetes components to head

Also delete the old flag, since it's unused.
