1. Add ask-data-insights tool based on conversational analytic API.
2. Add tokenSource for ask-data-insights tool, it uses access token
instead of client or restService.
3. Add a max row count to source, currently fixed to 50 and used only
for ask-data-insights tool. Later we may make it available for user to
make change and apply to bigquery-execute-sql and bigquery-sql to avoid
return too many data by accident.
