Add command line arguments for testing queries

[sarahyurick]

[UPDATED]
For local testing purposes, this allows the user to do something like:

pytest tests/unit/test_queries.py::test_gpu_query['q1.sql'] --runqueries --rungpu --data_dir "/home/nfs/syurick/dask-sql/tests/unit/data/sf1/parquet_2gb_sorted/" --queries_dir "/home/nfs/syurick/dask-sql/tests/unit/queries/"
