Process hangs during startup if Redis instance is not responding

[gergelypolonkai]

I tried to connect celery-exporter to a Redis based broker, which sits behind a firewall. Since i didn’t have my IP added to the firewall, i couldn’t connect to the Redis instance, which made celery-exporter hang without any response. After i added the IP to the firewall, it came up fine.

I would have expected a timeout error after a while, or at least an “Initial fetching of registered tasks”.
