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.

Inizia da python/ciqueue/_pytest/test_queue.py intorno alle righe 59-81 e analizza la configurazione del client Redis per individuare dove vengono configurati socket_timeout e socket_connect_timeout. Determina e documenta valori predefiniti espliciti per entrambi i valori, quindi aggiungi o aggiorna i test del client della coda per verificare che i client non attendano indefinitamente per impostazione predefinita.
