This introduces two new interfaces to airshipctl: * Bundle: represents a Kustomize rendered collection of your documents that allows you to iterate over or filter the documents in the bundle. * Document: a thin wrapper around a rendered document. This commit also includes a proposal for a way to represent YAML test fixtures as testdatafs.go and a new testdata subfolder within the document pkg.
