Add metric for sum of SHA1s

It is not possible to have a metric with a non-numeric value, so we
calculate the numeric representation of the SHA1. However, SHA1s are
too big to fit with a numeric data type, so a truncated version of the
numeric value is calculated.

The numerical calculation was taken from [1].
