> The BrokerProxy immediately recreates its simple consumer, and re-fetches
> when an exception is thrown in its fetch loop (inside its thread). We should
> add a backoff here. Rather than doing a fixed time (say sleep 10s), let's do
> an exponential backoff with a cap (0s, 100s, 200s, 400s, 800s, 1.6s, .. up to
> cap), so we don't introduce lag in the case where there's a one-off failure
> and an immediate reconnect would work.
> I suggest adding a config to allow the backoff time and max cap and to be
> defined, but default it to 100ms, and 10s, respectively.
