> minifi::utils::file::concat_path in FileUtils.h can only concatenate 2 file
> path parts which is very limiting. It has 3 parameters: 2 file path parts and
> a force_posix flag with a default value. This should be improved to have
> variadic arguments to be able to concatenate any number of file path parts.
