This introduces two configuration management runs into the
Vagrant provisioning phase. The first chef-solo run ensures that
a current version of chef is installed using the omnibus updater.
The second chef-solo run installs vim and phantomjs.
Much more is possible, this is a proof of concept.
Cookbooks are stored in the chef directory, and managed by
librarian-chef, which is like a bundler for cookbooks.
Chef is run when VM is first downloaded and booted, but not on
subsequent halt/up cycles. To force chef to run again, use
`vagrant provision`.
