list-objects-filter-options: create copy helper
As we add more embedded members with type 'struct
list_objects_filter_options', it will be important to easily perform a
deep copy across multiple such structs. Create
list_objects_filter_copy() to satisfy this need.
This method is recursive to match the recursive nature of the struct.
