BUG: Google BigQuery API Change
This is a placeholder for a commit I'm working on to resolve a recently introduced API bug with `pandas.io.gbq`. Basically, the module fails to handle result pagination properly, so result sets are limied to 10k rows. When #4140 was pulled, we were told by Google that this would be a backend fix that would not require changes on our parts. Unfortunately, there were some issues with bq.py (v 2.0.15) which we listed as a requirement for this package, so we will be needing to up that to v2.0.16 and fix some compatibility bugs around new code introduced. To reiterate, the only mandatory change at this point is upping the bq.py requirement `easy_install --upgrade bigquery`, though the 10k result set bug is crippling in our opinion so we're making it a high priority to fix.
