multiline-options: Allow multi_line_timeout set to a none integer value

The actual implementation. and validations restrict only the value to be higher than the `follow-freq` (ideally multiplication of it).
As the `follow-freq` can be much smaller than one second it makes sense to allow this value to be a non-integer value as well.
