Description

Currently, the SparkSQL UI page shows only actual metric info in each SparkPlan node. However with statistics info may help us understand how the plan is designed and the reason it runs slowly.

This issue is to show BroadcastHashJoinExec numOutputRows statistic info on SparkSQL UI page first when it's available.
