Allow choosing the metrics to report

[gouttegd]

When using the metrics command, instead of always reporting the same fixed set of metrics (number of contributors, number of opened issues, number of closed issues, etc.), it should be possible to select which metrics we are interested in.

This could possibly take the form of a new option (--metrics?) accepting a list of metrics. For example,

grh metrics --metrics opened_issues,commits

would only report the number of opened issues and the number of commits over the reporting period.

Awesome super useful!

Good to know there’s an interest.

As usual, no promises as to when this could become reality. :p
