      Description

      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.
