Description

ConfigurationUtils#convertToString is hard-coded to serialize instances of Duration into nanoseconds. This often produces output which isn't really human-understandable. It would be good to be a bit smarter here in how this is serialized to make it more natural to humans.

A possible solution could be choosing the lowest unit with which the value can be expressed as an integer, e.g. "1 min", "35 s", "3256 ms", …
