T1622: Install Kubernetes
Summary

Container runtime: CRI-O, requires libseccomp2 2.4+ from backports on Debian

The kubeadm, kubelet and kubectl executables should match the version of
Kubernetes. As such, the packages are marked on hold to avoid wild updates.

Ref T1622.

Test Plan

Tested on CloudHugger with salt-call --local state.apply

Let's stop the scope of this change at "deploy everything we need to be able to initialize the cluster".

That means:

  • install a way to communicate with runc (cri-o)
  • install kubectl, kubelet and kubeadm
  • tweak kernel
  • disable swap

ie this diff, but without roles/paas-kubernetes/kubernetes/cluster.sls (currently committed) and roles/paas-kubernetes/kubernetes/files/kubeadm.yaml (partially committed, partially uncommitted).
