After a power outage, when the network router is not yet up and running, connecting to the MQTT broker may fail with timeouts combined with OSError exceptions.
In such cases I have seen the following errors in the log:
OSError: [Errno 113] No route to host
In such a case, we need to retry connecting to MQTT, just like we do for a timeout.
Fixes deiger/Alarm#3
