* test scoped jdbc driver for druidtest:/// backed DruidAvaticaTestDriver
** DecoupledTestConfig is used inside the URI - this will make it possible to attach to existing things more easily
* DruidQuidemTestBase can be used to create module level set of quidem tests
* added quidem commands: !convertedPlan, !logicalPlan, !druidPlan, !nativePlan
** for these I've used some values of the Hook which was there in calcite
* there are some shortcuts with proxies(they are only used during testing) - we can probably remove those later
