Consumers: Unsubscribe topics from consumer group

[Boniker]

Issue submitter TODO list

• [X] I've searched for an already existing issues here
• [X] I'm running a supported version of the application which is listed here and the feature is not present there

Is your proposal related to a problem?

I noticed that the Kafka UI doesn’t have an opportunity to unsubscribe topics from consumer group.

Imagine a situation where you have a lag alert in your environment. If you reset the offset, the situation will not change because the lag will remain and the topic will be subscribed to this customer group

Describe the feature you're interested in

I request to be able to completely unsubscribe the topic from the customer group (like remove it from the cg)

AC:

• stop consumer group
• unsubscribe topics button for all topics
• start consumer group

Describe alternatives you've considered

we can do it via kafka server (better to do it via Kafka-ui):

kafka-consumer-groups --bootstrap-server <server>
   --delete-offsets -group <group_name> \
   --topic <topic_1> \
   --topic <topic_2> \
   --topic <topic_3>
