Subject: [PATCH] build(other): test deployment locally

Context
-------
There was a similar PR #1263 attempting to do the same with docker. I was running into isolation issues with docker (setting hostname not allowed in the container and some system folders are read-only) and learned that for this use case, an actual hypervisor would be better and vagrant is a conventional tool to set up these virtual machines.

Motivation
----------
On the weekend we had a downtime on production because `nginx` configurations got out of sync with the code in newer releases.

To prevent this and further downtimes I suggest to check in our deployment configuration and make it *reproducible*.

This PR is an attempt to create a virtual machine that behaves as similar as possible to production and can be used as a sandbox for changes to our deployment configuration.

How to test
-----------
1. Install [Vagrant](https://www.vagrantup.com/) on your machine

1. `cd deployment/local-testing`

1. `vagrant up` .. and wait

1. Following services are running:
   - <http://localhost:8000/>
   - <http://localhost:8000/api>
   - <http://localhost:8000/docs>
   - <http://localhost:8080/>
   - <http://localhost:8082/>

1. Be amazed

In the future we might want to use [Ansible](https://www.ansible.com/) for provisioning. We could run our playbooks against this virtual machine, too.
