Fixes "TypeError: Population must be a sequence." using random.sample()

[hiwakaba]

Hello, I am a kafka-python rpm packager.

I would like to fix "TypeError" in test/test_assignors.py using Python-3.11. The population of random.sample() must be a sequence and automatic conversion of sets to lists is no longer supported in Python-3.11.

<mock-chroot> sh-5.1# python3
Python 3.11.0b3 (main, Jun 24 2022, 00:00:00) [GCC 12.1.1 20220507 (Red Hat 12.1.1-1)] on linux

>>> from random import Random
>>> r = Random()
>>> r.seed('test')
>>> r.sample({'t1', 't10', 't2', 't3', 't4', 't5'}, k=4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python3.11/random.py", line 436, in sample
    raise TypeError("Population must be a sequence.  "
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Population must be a sequence.  For dicts or sets, use sorted(d).

I think we should pass the data as an instance of list or sorted set.

>>> r.sample(sorted({'t1', 't10', 't2', 't3', 't4', 't5'}), k=4)
['t1', 't4', 't3', 't5']
