Version & Environment

Redpanda version: (use rpk version): v22.1.3

What went wrong?

When consumer group is deleted we persist a checkpoint batch with null value - tombstone. Group is correctly deleted when redpanda is running. After a restart group is still listed by redpanda and its state is recoverable i.e. all committed offsets are not deleted correctly.

What should have happened instead?

Group should be deleted and when asked to describe it should return Dead status.

How to reproduce the issue?
