consumer group observability is not part of the managed service
as a developer I want to have out of the box tools to inspect, delete, modify consudmer groups so that I can troubleshoot environments.
Today you have to download and setup opensource kafka locally and work out a config file. The instructions in the documentation dont make this easy.
Some solutions can be
1. add listing, inspecting, deleting consumer groups to a webpage
2. a metric of the number of consumer groups should be considers in the overviews
3. Potentially solve by step by step instrucions and maybe giving an ability to download the config file required for opensource kafka
4. Competitors have some mature features to cover this and managing consumer groups is a daiily activity in working with this tech.
