OpenWhisk: Add Packaging an action as a Node.js module to the Table Of Contents (TOC)

[csantanapr]

Users are stating that would be good to have the section "Packaging an action as a Node.js module" in the TOC.

It would be an entry in: Creating and invoking actions -> Creating JavaScript actions -> Packaging an action as a Node.js module Linked to https://console.ng.bluemix.net/docs/openwhisk/openwhisk_actions.html#openwhisk_js_packaged_action
