Description

The current DeleteOffset API check relies on the consumer group's committed offsets to decide if a topic exists or not. While this works in most of the cases, it does not work when a topic exists but it does not have any committed offsets yet. Moreover, it is not consistent with other APIs which rely on the metadata cache so it must be updated.
