Delay message fetch attempt if the consumer is in errored state.
Delay message fetch attempt if the consumer is in errored state.

When the consumer gets disconnected from Kafka an attempt to fetch
a message fails almost instantly, so we get into a tight loop
unless we add the a delay before the next attempt. That causes
a worker to die.
