ImportWarning in Python 3.10

Describe the bug

When using aiokafka with Python 3.10 with warnings enabled, several warnings are emitted.

Expected behaviour

No warnings are emitted.

Environment (please complete the following information):
python 3.10.4, aiokafka 0.8.0, fresh conda env

❯ conda create -n blah python=3.10.4
❯ conda activate blah
❯ pip install aiokafka
...

Try python -Werror -c 'import aiokafka' to see the source of problem is in python-kafka. Here is an issue dpkp/kafka-python#2282, and even a pull request dpkp/kafka-python#2304 to fix it.
