> When we shut down a Drillbit, we should provide some options similar to those available from Oracle's shutdown command (see https://docs.oracle.com/cd/B28359_01/server.111/b28310/start003.htm#ADMIN11156) .
> At present, in order to avoid problems like DRILL-2654, we try to do a short wait for executing queries, but that times out after 5 seconds, and doesn't help with long-running queries.
> Someone that is running a long query might be unhappy about losing work for something that was near completion, so we can do better.
> And, in order to avoid spurious cleanup problems and exceptions, we should explicitly cancel any remaining queries before we do complete the shutdown.
> As in the Oracle example, we might have shutdown immediate issue cancellations to the running queries.  A clean shutdown might not have a timeout, or might allow the specification of a longer timeout, and even when the timeout goes off, we should still cleanly cancel any remaining queries, and wait for the cancellations to complete.
