Implement function to calculate Recall metric
As specified in proposal #5794 we need to implement a function to calculate the Recall metric.

Ideally the function should be part of the private interface and called only through the `calculate_metrics` function (see #6063). `_calculate_recall()` could be a nice name.

For more detailed information check out the original proposal.
