Uninstallation of the Collaboration Manager

We're sorry to see you go
If you have any suggestions for us to improve, please share them with us. Either privately via set@deutschebahn.com or via a Github issue.

If you want to uninstall the management portal, you can run the following comment:
```
helm uninstall <release-name> -n <namespace> helm
```
or delete the management portal namespace:
```
kubectl delete namespace <namespace>
```
The previous command doesn't clean the sessions namespace. Please clean it manually by running (this does also remove all persistent workspaces!):
```
kubectl -n <sessions-namespace> delete all --all
```
or just delete the namespace:
```
kubectl delete namespace <sessions-namespace>
```
