    I've now switched JdbcIOIT to do a write then a read. This code:
    * creates a table during test class setup (this runs on the client)
    * during the write test, generates data and populates data into that table
    * reads the data from the table and verifies it via HashingFn + count
    
    I really like the data generation - feels very clean, and I love the fact that using CountingSource means this part can be parallelized for larger data sets. I suspect that we may choose to refactor the "generate data" portion out into a helper method alongside HashingFn in io-common.
