[BUG] KubeBlocks Uninstall - CRDs delete gets stuck

[gstefanoff]

Describe the bug
Installed KubeBlocks (version 0.9.2 ) via helm using these instructions

When I tried uninstalling with helm, I was not able to delete CRDs. Every attempt resulted in delete processes being stuck. I am not able to delete the namespace because k8s is waiting for 23 resources to be removed, the problem is I cannot remove them either because they get stuck as well the only solution, I have not tried yet is the one mentioned here.

To Reproduce
Steps to reproduce the behavior:

1. Delete pods (posgres, redis)
2. Uninstall addons used
3. helm uninstall kubeblocks --namespace kb-system
4. kubectl get crd -o name | grep kubeblocks.io | xargs kubectl delete
5. kubectl delete namespace kb-system

Expected behavior
KubeBlocks should be as easily removed as it is installed. Having to resort to "workarounds" such as removing finalizers is not feasible solution.

Screenshots

Not actually deleted!

Additional context
logs from kb-system namespaces pending deletion.

Hi @gstefanoff

It seems even though you uninstall addons, resources like actionssets, addons are not deleted actually.

1. may I know how do you uninstall addons?
2. have you deleted all clusters properly before uninstall addons ? (e.g. k delete cluster )
