RedisCluster is on EOL

[XayOn]

RedBeat uses redis-py-cluster.
It's been 2 years since main redis-py project has incorporated cluster support.

References

redbeat/redbeat/schedulers.py

Line 143 in 5d1d5c1

connection = RedisCluster(decode_responses=True, **redis_options)

Fix

A simple

from redis.cluster import RedisCluster

Should do the trick.

Note that this would drop support to redis-py < 4.1, but will avoid potential issues with unmantained redis-py-cluster
