Stream NSQ messages to Google's BigQuery using the streaming API.

Written by Eran Sandler (@erans)

This is a very early version that does work but was not (yet) tested in real hard production environment.

• Message body is a valid JSON that is a flat dictionary (only key and simple values).
• Each message must contain data that will constitute a single row that will go into BigQuery.
• BigQuery table MUST exists and the schema MUST match the JSON being sent.
• This version sends each message in its own request and does not use any batch API (yet).
