**Is your enhancement request related to a problem? Please describe.**
If you want to manually adjust the topic distribution, you need to know which bundles the topic is on, and then uninstall the bundle to reach the topic migration.
At present, the corresponding bundle can be found through topic,the command is "pulsar-admin topics bundle-range", but there is no tool to find the mapping topic through the bundle.

> Pulsar calculates which bundle it belongs to according to the hash value of topic, getting all topics in the bundle maybe not be supported.
In fact broker have already cached the topics belongs to each bundle in memory, we can easily support it

You can get the topic list in a bundle, or list all bundles with their topics under a namespace for one broker.

Pulsar does not store all topic metadata in order to save the storage pressure of metadata.
Pulsar calculates which bundle it belongs to according to the hash value of topic, getting all topics in the bundle maybe not be supported.

Thanks, But There are some questions:
1. The cache does not represent accurate raw data, does it?
2. Only when topic is active can get it?
3. In ZK, the node storing topic metadata is temporary?
