Add support for 'group' and 'having' keys in smart filters (#1286)

* Add support for 'group' and 'having' keys in
SmartFilterMixin

- fixes #1285

* Add `group` and `having` fields to `additionalFields` list in `FilteringType` class

- This should allow passing the parsed filters back into `search()`.
