There are already options to disable certain planner rules in the RecordQueryPlanConfiguration. However, that is not currently exposed through the Relational (JDBC) interface. We should add some Options to the query/connection that allow that to happen.

While we are there, we should make it easy to disable the new plan rewrite rules that are going in (see #3401). Those rules fundamentally shift the way that more complicated queries get planned, and they could have significant performance implications. Therefore, it would be good to expose a way to disable all of those new rules at once.
