[VOTE] KIP-727 Add --under-preferred-replica-partitions option to describe topics command

[wenbing shen]

Hi all,

I'd like to start a vote on KIP-727 to add two options (--non-preferred-leader 
and --non-preferred-leader-json) in TopicCommand to directly get the list of 
partitions whose leader is in the non-preferred replica and support to output 
it to json format.

Thanks,
