Before this change options were read and set in native format. This means for example nanoseconds for durations or an integer for enumerated types, which isn't very convenient for humans. This change enables these types to be set with a string with the syntax as used in the command line instead, so `"10s"` rather than `10000000000` or `"DEBUG"` rather than `8` for log level.
