Subject: [PATCH] pkg/generator: Add prune to Gopkg.toml template

The code that gets vendored by dep by default is huge. We can
leverage the functionality given by dep viz. prune. This will remove
all the non-go code and unused packages.

It makes an exception to the k8s.io/code-generator repository. Since
we use the scripts from this repository to generate code.
