Summary of changes:
* Output any error from Mkdir in `helmfile template`
* Add failing test for .Release.Name interpolation
* Add golden files for testing
* Parse resources with kustomize to compare them structure by structure
* Decode resources into plain maps
The RNode type from kustomize uses yaml.Node under the hood,
which carries extra information like line numbers, which
become noisy when comparing with deep.Equal.
