Bootstrap Packer template for libvirt and Vbox (#48)

This PR contains a provisioning mechanism for the Vagrant boxes we ship
as part of Sandbox.

In order to self contain and distribute the required dependencies for Tinkerbell
and Sandbox without having to download all of them runtime we decided to use
[Packer.io](https://packer.io) to build boxes that you can use when provisioning
Tinkerbell on Vagrant.

Currently the generated boxes are available via [Vagrant
Cloud](https://app.vagrantup.com/tinkerbelloss).

+This directory contains a provisioning mechanism for the Vagrant boxes we ship
+as part of Sandbox.
+
+In order to self contain and distribute the required dependencies for Tinkerbell
+and Sandbox without having to download all of them at runtime we decided to use
+[Packer.io](https://packer.io) to build boxes that you can use when provisioning
+Tinkerbell on Vagrant.
+
+Currently the generated boxes are available via [Vagrant
+Cloud](https://app.vagrantup.com/tinkerbelloss).
+
+---
+
+## Build
+
+To build the boxes checkout the right directory and run
+
+```terminal
+$ packer build --parallel-builds=1 ./template.json
+```
+
+`-parallel-builds=1` is required because the template builds images for multiple
+providers using the [Vagrant
+builder](https://www.packer.io/docs/builders/vagrant) and I didn't manage to get
+it to work in parallel yet.
+
+## Deploy to Vagrant Cloud
+
+I didn't find a way to make the Vagrant Cloud post processor to work. But I use
+the vagrant cli `vagrant cloud publish` command.
