[SPARK-14628][CORE][FOLLLOW-UP] Always tracking read/write metrics

## What changes were proposed in this pull request?

This PR is a follow up for https://github.com/apache/spark/pull/12417, now we always track input/output/shuffle metrics in spark JSON protocol and status API.

Most of the line changes are because of re-generating the gold answer for `HistoryServerSuite`, and we add a lot of 0 values for read/write metrics.

## How was this patch tested?

existing tests.
