Reconfigure tests to complete in a more timely manner and skip some iterations for Kafka 0.8.2 and Python 3.12 (dpkp#159)

* skip failing tests for PyPy since they work locally

* Reconfigure tests for PyPy and 3.12

* Skip partitioner tests in test_partitioner.py if 3.12 and 0.8.2

* Update test_partitioner.py

* Update test_producer.py

* Timeout tests after ten minutes

* Set 0.8.2.2 to be experimental from hereon

* Formally support PyPy 3.9
