Support for CooperativeStickyAssignor

**Describe the solution you'd like**
I'd like to have support for [CooperativeStickyAssignor](https://kafka.apache.org/25/javadoc/org/apache/kafka/clients/consumer/CooperativeStickyAssignor.html). Support for StickyAssignor is already implemented [here](https://github.com/aio-libs/aiokafka/blob/5ec91e769147699322591e641e31107dfea65d29/aiokafka/coordinator/assignors/sticky/sticky_assignor.py#L668).
