Review comment:
@bob-barrett It totally makes sense to not block it the auto preferred
leader election if there is any ongoing reassignments in the cluster. However,
I wonder if we should continue to disallow it for the partitions being
reassigned in order to not mess up with the their ongoing reassignment. I am
not sure if this is a real concern or not though. Have you thought about this
case?
