fix for discovery document upload timeout failure

[byrne-greg]

Problem Description

When a user executes npm run train, during the document upload phase, they will see the following error:

manualdocs/manual_0.json { Error: Callback function "uploadDocumentAsync" timed out.
    at Timeout.timeoutCallback [as _onTimeout] (/**/*/WatsonAssistantWithDiscoveryOpenWhisk/node_modules/async/dist/async.js:4916:26)
    at ontimeout (timers.js:458:11)
    at tryOnTimeout (timers.js:296:5)
    at Timer.listOnTimeout (timers.js:259:5) code: 'ETIMEDOUT' }

(see issue #43).

Solution

The default configuration file that was used when creating the Discovery collection was configured to use the older AlchemyLanguage enrichments. As of the migration, when anyone attempted to upload documents, they would receive the above error.

The default configuration file used during the train-discovery.js script was changed to use the NLU enrichment technology.
