### Rationale for this change While implementing Flight SQL for https://github.com/influxdata/influxdb_iox, it took me a while to realize we could pass the equivalent of our "catalog name" via a JDBC URL parameter. It turns out it works great! This was also not clear to me when contributing to the mailing list discussion on catalog support either https://lists.apache.org/thread/fd6r1n7vt91sg2c7fr35wcrsqz6x4645 ### What changes are included in this PR? 1.
