add setup using vagrant and virtualbox and support for python 2.7

Hi, I saw your project(edge) and I really liked.

However I'm still on python 2 and I wanted to use edge for python 2. Thus I created this fork. Maybe in your project you could point people who want python 2 compatibility over here.

I also added vagrant/ansible devops.

cheers,

Komu W.

Thanks Komu. The devops part was really fantastic. I am working on adding Python 2.x compatibility into the project. Hope to include it in the next release soon.

@arocks Hi, Thanks for the kind words.
It's great that you plan on supporting python2 in the next release. I hope that very soon we will all move to the land of milk, honey and python3.
