This is a nice update @artem-aliev because it doesn't change API and it is
general for all `GraphComputer` implementations. Great! A couple things please
for a solid VOTE.
1. Please update the `CHANGELOG.asciidoc` with the change you made.
2. In this PR discussion, please provide a `CUT/PASTE` of what the new
metrics `toString()` looks like so people can judge its merits.
Thank you.---
