Migrated virtual machine test settings to test kitchen instead of plain vanilla Vagrant.  This is because berkshelf-vagrant is deprecated, due to the morass of Ruby dependenies and fragility of the Vagrant plugin system.  Test-kitchen is compatible with cloud providers and bare metal so is a better solution.
Merge branch 'master' of https://github.com/scarolan/chef-dev-workstation
Renamed kitchen.yml file, updated .gitignore.
