Vagrant is a tool for building and distributing development environments.

Vagrant::Config::VersionBase.merge

Merges two configuration objects, returning the merged object.
The values of `old` and `new` are the opaque objects returned by
{load} or {init}.

Once again, the return object is treated as an opaque value by
the Vagrant configuration loader, so it can be anything you'd like.
