Introduce datastructures from committime cleanup

[KevinMGranger]

I'm splitting up #720 into pieces so it's easier to review. This is an unobtrusive change, just copying over datastructures from that PR. (And unit tests for one of them).

Side note: make unit-tests gives me a bunch of ModuleNotFoundError: No module named 'exporters' errors. What gives?

This is a replace of CommitMetric right?

If so, please checks the changes here #900 so they are also applied here

And if you want, you can look into this issue #903

[KevinMGranger]

It is not a replacement, but is part of the replacement input.

Mind if I ask a few more questions in #900?
