Adds a `make release` command for releasing new NPD version. It stops
pushing the tar files to gs://kubernetes-release, because no one has
write permission to the GCS bucket any more. We haven't pushed NPD tar
files to that GCS bucket after v0.8.10. k/k has been using NPD v0.8.13+
since 1.29. NPD release should just include the tar files in the release
note.
There are a few things that need to be done for each release. This adds
some basic notes to help make sure all steps are followed. This is a
working document, so hopefully it will be expanded over time as we
identify other steps that should be done.
