`make quick-release-images KUBE_BUILD_CONFORMANCE=n` was broken since we
modified hyperkube to use actual binaries from a script. Temporarily
build the two additional binaries needed until we remove hyperkube image
completely. Added a TODO as a reminder
Pick up some code from https://github.com/heptio/kube-conformance
Fix up build scripts for the new conformance image
Fix Header template and Copyright to make verify job go green
update README and add execute permissions for script
