Dave Borowitz cfd221eede Add script to pack npm_binary tarballs with dependencies
Contrary to our experience with bower, not all packages on
registry.npmjs.org come with dependencies bundled. This script
produces a tarball with bundled dependencies which can be hosted on
the Gerrit GCS bucket and used as an npm_binary.
