Enable chrome to poll the API to handle the pdf generation lifecycle. When a PDF is requested through the `/v2/create` endpoint, an ID is returned. Using that ID, the `/v2/status/:ID` endpoint can be used to get a json object containing the status of the generation. When the status of the object is 'Generated', you can fetch the full rendered PDF with the same ID at the `/v2/download/:ID` endpoint.

AC:
Chrome can fetch a rendered PDF from the API
Chrome can do smart enough polling on the status object
