libvirt-coreos is a cluster provider for kubernetes that starts local VMs and
runs kubernetes on it.
Its goal is to provide a multi-machines environment to develop and test kubernetes.
The purpose is mostly the same as the vagrant provider but with a big focus on
efficiency. The vagrant cluster takes a long time to boot and consumes a huge
amount of disk space. libvirt-coreos aims at being cheaper. As a consequence,
libvirt-coreos allows to start bigger clusters with more minions than vagrant.
When no args are passed to a script, "$@" is unset,
which causes a shell error in "nounset" mode.
This change passes an empty string to kubectl in that case
so it can print help.
Force kubectl to the git repo version if we detect a built version.
Add a KUBECTL_PATH override so that system/home directory versions of
kubectl can be used if desired. Remove existing $HOME inference.
Also fix up cert generation. It was failing during the first salt highstate when trying to chown the certs as the apiserver user didn't exist yet. Fix this by creating a 'kube-cert' group and chgrping the files to that. Then make the apiserver a member of that group.

* Rewrite a bunch of the hack/ directory with modular reusable bash libraries.
* Have 'build/*' build on 'hack/*'. The stuff in build now just runs hack/* in a docker container.
* Use a docker data container to enable faster incremental builds.
* Standardize output to _output/{local,dockerized}/bin/OS/ARCH/*. This regularized placement makes cross compilation work.
* Move travis specific scripts under hack/travis
With new dockerized incremental builds, I can do a no-op `make quick-release` in ~30s. This is a significant improvement.
