Add bare-metal Fedora Atomic module

* Several known hacks and broken areas
* Download v1.10 Kubelet from release tarball
* Install flannel CNI binaries to /opt/cni
* Switch SELinux to Permissive
* Disable firewalld service
* port-forward won't work, socat missing

+
+Typhoon is a minimal and free Kubernetes distribution.
+
+* Minimal, stable base Kubernetes distribution
+* Declarative infrastructure and configuration
+* Free (freedom and cost) and privacy-respecting
+* Practical for labs, datacenters, and clouds
+
+Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
+
+## Features <a href="https://www.cncf.io/certification/software-conformance/"><img align="right" src="https://storage.googleapis.com/poseidon/certified-kubernetes.png"></a>
+
+* Kubernetes v1.10.0 (upstream, via [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube))
+* Single or multi-master, workloads isolated on workers, [Calico](https://www.projectcalico.org/) or [flannel](https://github.com/coreos/flannel) networking
+* On-cluster etcd with TLS, [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/)-enabled, [network policy](https://kubernetes.io/docs/concepts/services-networking/network-policies/)
+* Ready for Ingress, Prometheus, Grafana, and other optional [addons](https://typhoon.psdn.io/addons/overview/)
+
+## Docs
+
+Please see the [official docs](https://typhoon.psdn.io) and the bare-metal [tutorial](https://typhoon.psdn.io/bare-metal/).
