        The import stage will receive a HarvestObject object and will be
        responsible for:
            - performing any necessary action with the fetched object (e.g
              create a CKAN package).
              Note: if this stage creates or updates a package, a reference
              to the package must be added to the HarvestObject.
              Additionally, the HarvestObject must be flagged as current.
            - creating the HarvestObject - Package relation (if necessary)
            - creating and storing any suitable HarvestObjectErrors that may
              occur.
            - returning True if everything went as expected, False otherwise.
