Performance Testing

[awm33]

Ideally, we would have a script/CLI that could test / simulate different loads

• Testing for load size in rows (10k, 100k, 1m, 10m etc rows)
• Testing for load currency in number of tables (as well as num rows)

This work can be seen in datamill-co/target-snowflake#14. We could turn this into a testing library (which could simplify a lot of the shared tests between targets).
