> Driver.run is the highest level method which all queries go through, whether
> they come from Hive Server, the CLI, or any other entry. We also do not have
> any hooks before the compilation method is called, and having hooks in
> Driver.run would provide this. Having hooks in Driver.run will allow, for
> example, being able to overwrite config values used throughout query
> processing, including compilation, and at the other end, cleaning up any
> resources/logging any final values just before returning to the user.
