Update install instructions to include vagrant
What does this MR do?
Updating the README to include instructions to use a vagrant vm for users that cannot use the normal docker-compose setup.
How confident are you it won't break things if deployed?
It won't break production as its only the dev setup. I am not convinced all the setup instructions will work out the box though.
