VE-551 New Relic & Parsoid

Requirements for this to actually stop showing metrics for `GET /` in New Relic:

* [ ] Run `sudo npm update newrelic --save` on parsoid-s1
* [ ] Update package.json (if it is version locked)
* [ ] Update Chef @justinmhunter
* [ ] Add this line to your localsettings.js (if you wish to turn on newrelic) `parsoidConfig.newRelic = true;`
