Murad M updated KAFKA-7930:
---------------------------
    Description: 
StreamsResetter deletes the topics considered internal. Currently it just 
checks the naming as per 
[code|https://github.com/apache/kafka/blob/1aae604861068bb7337d4972c9dcc0c0a99c374d/core/src/main/scala/kafka/tools/StreamsResetter.java#L660].
 If assumption is wrong (either topic prefix or suffix), tool becomes useless 
if aware even dangerous if not. Probably better either:
 * naming assumption should be optional and supply internal topics with 
argument (--internal-topics)
 * deletion could be optional (--no-delete-internal)

Faced this, when was trying to reset applications with GlobalKTable topics 
named as *-changelog. Such topics sometimes are not desirable for deletion.
