Generated doc pages are missing nested config items

[zbjornson]

This is probably a more general issue than just googleapis/nodejs-compute, but if you look at e.g. the generated doc page for zone.createVM https://cloud.google.com/nodejs/docs/reference/compute/0.9.x/Zone#createVM
there are only three parameters: name, config and callback -- the config.* sub-parameters os, http, https and others are missing:

nodejs-compute/src/zone.js
