hmm I guess adding this data to the package.json under some key like `"jetpack-options` wouldn't be awful.  This does require more work for the automation side however, b/c a script will have to copy the addon folder to a temp directory then modify the read, parse, and modify the package.json then remove the temp directory in order to auto generate xpis for `run` or `test`.  Instead of merely adding a json file, zipping the cwd, and removing the json file.
