What changes were proposed in this pull request?

Current implementation uses shuffleSortTaskDeque.size() as current sorting file count.This value might be more appropriately described as the sort tasks waiting to be submitted to fileSorterExecutors. And the actual current sorting file number ( doing some disk-io operation etc) should be get from sortingShuffleFiles.

Why are the changes needed?

Add metrics to monitor current sorting files which is making disk-io operations.

Does this PR introduce any user-facing change?

No

How was this patch tested?

LGTM overall. The new metric should be added to the grafana dashboard. You can change the main branch's grafana asset file.
