urllib3 Retry API change

[mgberg]

As of urllib 2.0.0 (released 2023-04-26), the method_whitelist argument for Retry (which has been deprecated for a while) was removed in favor of allowed_methods.

However, the removed argument is still referenced here:

agraph-python/src/franz/miniclient/backends/requests.py

Lines 36 to 39 in 25b8963

	retries = Retry(backoff_factor=0.1,
	connect=10, # 10 retries for connection-level errors
	status_forcelist=(), # Retry only on connection errors
	method_whitelist=False) # Retry on all methods, even POST and PUT

Therefore, pinning the version of urllib3 is required. It would be great if this long-deprecated, now removed argument was replaced with the proper one.
