dataset.list_tables max_results parameter

[OmriBromberg]

I'm using great_expectations to test my data in BigQuery and the library introspects the entire database/schema for tables, meaning they use the function sa.inspect(engine).get_table_names(), because I have alot of tables this process is very very slow, I want to change the max_results parameter passed on to dataset.list_tables operation, when tested it increased performance dramatically

max_results doesn't really do what we want. We really want page_size.

See googleapis/python-api-core#194

api_core has been updated. There's a bigquery PR: googleapis/python-bigquery#686
