Dalton Hubble c42139beaa Update etcd from v3.3.14 to v3.3.15
* No functional changes, just changes to vendoring tools
(go modules -> glide). Still, update to v3.3.15 anyway

Dalton Hubble 1409bc62d8 Remove download_protocol variable from Fedora CoreOS
* For Fedora CoreOS, only HTTPS downloads are available.
Any iPXE firmware must be compiled to support TLS fetching.
* For Container Linux, using public kernel/initramfs images
defaults to using HTTPS, but can be set to HTTP for iPXE
firmware that hasn't been custom compiled to support TLS

Dalton Hubble 339e323491 Temporarily turn off QoS cgroups on Fedora CoreOS controllers
* Kubelets can hit the ContainerManager Delegation issue and fail
to start (noted in 72c94f1c6). Its unclear why this occurs only
to some Kubelets (possibly an ordering concern)
* QoS cgroups remain a goal
* When a controller node is affected, bootstrapping fails, which
makes other development harder. Temporarily disable QoS on
controllers only. This should safeguard bring-up and hopefully
still allow the issue to occur on some workers for debugging

Dalton Hubble 5fdeb9bc78 Adjust Fedora CoreOS image locations
* 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

Dalton Hubble 72c94f1c6a Add Kubelet System Container and bootkube bootstrap
* 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

Dalton Hubble aab14c5573 Run etcd-member.service across controllers
* Running the etcd container with NOTIFY_SOCKET mounted
(to use systemd Type=notify) causes podman to hang so
for now just use exec
