Run Docker in Nanoserver

This is a work in progress using Matt Wrock's NanoServer Vagrant box from Atlas and some half manual provisioning.

Build the Vagrant box

cd build
./build.sh
vagrant box add nanoserver_docker nanoserver_docker_virtualbox.box
cd ..

vagrant up --provider virtualbox
export DOCKER_HOST=tcp://127.0.0.1:2375
docker version
