* Use the xz compressed images published by Fedora testing,
instead of gzippped tarballs. This is possible because the
initramfs now supports xz and coreos-installer 0.8 was added
* Separate bios and uefi raw images are no longer needed
* First semi-working cluster using 30.307-metal-bios
* Enable CPU, Memory, and BlockIO accounting
* Mount /var/lib/kubelet with `rshare` so mounted tmpfs Secrets
(e.g. serviceaccount's) are visible within appropriate containers
* SELinux relabel /etc/kubernetes so install-cni init containers
can write the CNI config to the host /etc/kubernetes/net.d
* SELinux relabel /var/lib/kubelet so ConfigMaps can be read
by containers
* SELinux relabel /opt/cni/bin so install-cni containers can
write CNI binaries to the host
* Set net.ipv4_conf.all.rp_filter to 1 (not 2, loose mode) to
satisfy Calico requirement
* Enable the QoS cgroup hierarchy for pod workloads (kubepods,
burstable, besteffort). Mount /sys/fs/cgroup and
/sys/fs/cgroup/systemd into the Kubelet. Its still rather racy
whether Kubelet will fail on ContainerManager Delegation
