Create a new environment to support the initial date to get the history

It is very good, if you have an environment that we can set how long the exporter should look back.

Example: I need to get the history of commits from all repos, but today I can't do that.

Could you add that?

This exporter is actually not a reporting tool as it exports live data to a time series database (prometheus format).

Maybe it's better to create an own reporting tool but keep in mind that commits are not a valid KPI :)
