KUDU-2162 Expose stats about scan filters This patch adds the following resource metrics to scanners. - bytes read, from disk or cache - duration scanner was open in nanoseconds - wall time, cpu time and system time in nanoseconds These metrics can be used to roughly compare the amount of work done by scan operations, and could be useful for runtime optimizations in query planners like Impala or Spark.
