What this PR does
I've spent some time testing how the write path behaves when the Kafka-compatible backend has partial or full outages, in particular focusing on the cluster metadata update period. In this PR I'm updating the comment about it with what I learned. TL;DR is that it's good to have a low max age, but we can safely increase the min age to the same value to also get the const load property (default min age is 5s, so I'm proposing to increase it from 5s to 10s).
