e2e: enable reinstalling pretty much everything on VMs

[askervin]

• If a reinstall variable is set for any package, it will be forced to reinstall on the system.
• OpenSUSE / SLES install runc from Virtualization_containers.
• Reinstalling k8s means scrapping and recreating the cluster on VM -- in addition to reinstalling kubeadm, kubectl and kubelet.
• Refactor: get rid of screen-install-k8s.

Implemented on top of #688.

Implements suggested reinstall feature in issue #686 .
