As described in #194, sometimes when rolling out a new controller in a legacy cluster you may expect to temporarily have errors like
failed to sync service-per-pod "apps/v1:StatefulSet:staging:kafka": can't reconcile children for StatefulSet staging/kafka: [services "kafka-1" already exists, services "kafka-2" already exists, services "kafka-3" already exists, services "kafka-0" already exists]
which you can fix by deleting the existing resources (or doing hacky reparenting like described in #194).
However, if you're trying to fix this by deleting the existing resource, you might want resyncing to happen faster, so that the deleted resource gets replaced quickly. But you don't necessarily want to set all resyncs to happen fast.
Thus, it would be helpful if you could configure metacontroller with a smaller resync period after an error reconciling children than after success.
