> JobTrackerMetricsSource and QueueMetrics provides users with some metrics, but its naming rules( "jobs_running", "running_maps", "running_reduces") sometimes confuses users. It should be standardized.
> One concern is backward compatibility, so one idea is to share MetricMutableGaugeInt object from old and new property name.
> e.g. to share runningMaps from "running_maps" and "maps_running".
