@brian-brazil I've updated metrics according to [Metric and label naming](https://prometheus.io/docs/practices/naming/) and [Instrumentation](https://prometheus.io/docs/practices/instrumentation/) articles. Also, I've updated the metric description (some of them disabled by default).

@brian-brazil yes, I'll update PR shortly.

@smiklosovic Thank you for the comments. Do you agree with the proposed solution design? Do you have any comments on that?

Can we also add a benchmark that emulates rescaling during updates? e.g. `LatencyTrackingBench`

We should update the `.build/README.md` as we've removed `dtest-offheap` and added `dtest-latest`. It's worth mentioning `build-jars.sh` as well.

@belliottsmith I've addressed your comments, please, take a look again :-)

@belliottsmith Hi Benedict, have you had a chance to look at the comments that have been fixed? :-)

@belliottsmith Hi Benedict, I think we are really close to fixing it! :-) Would you mind taking one last look?
