Test Kitchen VagrantFile.rb to add disks & test_helper.bash to format them

Test Kitchen Add Vagrant Disks.md

Use these two files to add disks to your VMs (here adding three disks) when Kitchen spins up Vagrant boxes.

• test_helper.bash (add to your bats test with load test_helper)
• vagrantfile.rb (add to your .kitchen.yml using)
