-------------------------------------------------------------------
[~mjsax], After revisiting code, got 2 points in mind. Can you please help me
in understanding, which one is valid.
1) As described in the ticket , we need to print only "internal topic". Does
this mean we need to expose InternalTopologyBuilder#internalTopicNames Set,
that got added through `InternalTopologyBuilder#addInternalTopic`
2) As mentioned in your comment, repartition topic and changelog topic
constitutes internal topics. Can we call `InternalTopologyBuilder#topicGroups`
and read `InternalTopicConfig#name` field from both repartitionTopics,
stateChangelogTopics and print them.

> Add ability to print all internal topic names

> Key: KAFKA-6964
> URL: https://issues.apache.org/jira/browse/KAFKA-6964
> Project: Kafka
> Issue Type: New Feature
> Components: streams
> Reporter: Bill Bejeck
> Assignee: Jagadesh Adireddi
> Priority: Major
> Labels: needs-kip
>
> For security access reasons some streams users need to build all internal
> topics before deploying their streams application. While it's possible to
> get all internal topic names from the {{Topology#describe()}} method, it
> would be nice to have a separate method that prints out only the internal
> topic names to ease the process.
> I think this change will require a KIP, so I've added the appropriate label.
