Update reviews with Watson NLU about agfzb-cloudappdevelopment_capstone HOT 4 CLOSED

Since the NLU service was connected to the app, I tried using just the endpoint URL with instance/service ID, but no dice.
All the results are returned with "unauthorized" - meaning an APIKEY needs to get involved somewhere, as suspected.

(Unless there's a different step missing in the step where I connect the services... VCAP_SERVICES seems to be holding onto some creds.)

Quick notes on env vars/accessing them:

"""
VCAP is a dict
-- NLU []
----another dict in which 'credentials'{} sits
-------then in there is the apikey and url.
