docs: Create a new zone. Pass a list of keywords and their values to
          configure. For the list of keywords available for zone configuration,
          see :attr:`ns1.rest.zones.Zones.INT_FIELDS` and
          :attr:`ns1.rest.zones.Zones.PASSTHRU_FIELDS`
          If zoneFile is passed, it should be a zone text file on the local disk
          that will be used to populate the created zone file.
