BUG: Pagination in pandas.io.gbq
In light of some last minute API changes in Google BigQuery, I have updated our code to function properly. In particular, this fixes a known bug that limited result sets to 10,000. Hopefully we'll have an entirely new version soon that will make better use of Google's reference code and thus be more future proof. Note that bigquery v2.0.17 is new as of today... 2.0.16 tested fine, but they fixed a few important backend things so we went ahead and made the change mandatory in light of the pandas release candidate.
