chore: add a vagrant config for testing

I used these images to play around with the installer. Might be useful for more people.

I think that's fine 👍 do you need it installed with the RPM (mentioned in the spec file) or just running from source/git ?

[bruno-fs]

only needed when running from source. I think adding it to the RPM would be too much

I'd like to see a README or DEVELOPMENT doc or at least some inline comments somewhere to explain to future readers why this Vagrantfile exists and how to use it. Otherwise, it seems really strange and unexpected to be here.
