[SPARK-25451][CORE][WEBUI]Aggregated metrics table doesn't show the right
number of the total tasks
## What changes were proposed in this pull request?
Total tasks in the aggregated table and the tasks table are not matching
some times in the WEBUI.
We need to update the executor summary of particular executor, when ever
last task of that executor has reached. Currently it update based on last task,
of all the executor. So, some particular executor task might miss, because for
live application we update after some period.
## How was this patch tested?
Tests to reproduce:
```
bin/spark-shell --master yarn --conf spark.executor.instances=3
sc.parallelize(1 to 10000, 10).map{ x => throw new RuntimeException("Bad
executor")}.collect()
```
