Use DiffService.DiffStats RPC when calculating added and removed lines of a diff
Currently we iterate over DiffLine
's and count parsed added and removed lines.
With this information coming directly from git diff --numstat
on DiffStats
RPC, there's no need to keep doing that.
This same method is used to present added / removed lines of each diff file on /diffs
page.
