Description

If there is no leader for a partition, the Metadata API returns an empty ISR. When using the `--bootstrap-server` option with `kafka-topics.sh`, this leads to the following output:

Topic:foo       PartitionCount:1        ReplicationFactor:2     Configs:segment.bytes=1073741824
        Topic: foo      Partition: 0    Leader: none    Replicas: 1,3   Isr: 

When using `--zookeeper`, we display the current ISR correctly:

Topic:foo       PartitionCount:1        ReplicationFactor:2     Configs:
        Topic: foo      Partition: 0    Leader: -1      Replicas: 1,3   Isr: 1

To avoid confusion, we should make this output consistent or at least not misleading. We should either change the Metadata API to print the ISR when we have it or we can change the output of the topic command to `N/A` or something like that.
