Sensible Defaults for Python Redis Client

By default no timeouts are set for the Redis client. It's poorly documented, but as far as I can tell, the Redis client will wait hang infinitely by default. This is not a sensible default for ci-queue clients, forcing every client to specify this value. socket_connect_timeout defaults to whatever is specified for socket_timeout, but since that is handled deep down in the Redis client and certainly not documented by ci-queue a responsible client might not rely on that.

I suggest explicitly setting sensible defaults for these two values to reduce the burden on clients.

Beginne mit python/ciqueue/_pytest/test_queue.py etwa in den Zeilen 59-81 und untersuche die Einrichtung des Redis-Clients, um festzustellen, wo socket_timeout und socket_connect_timeout konfiguriert werden. Ermittle und dokumentiere explizite Standardwerte für beide Werte und füge dann Tests für den Queue-Client hinzu oder aktualisiere sie, um zu überprüfen, dass Clients standardmäßig nicht unbestimmte Zeit warten.
