Fix Deseeding of Service User

[BugRoger]

When a cluster is deleted the service user needs to be cleaned up

I think this is already implemented. See

kubernikus/pkg/controller/ground.go

Lines 293 to 296 in cb6c9f3

	glog.Infof("Deleting openstack user %s@%s", tpr.Spec.OpenstackInfo.Username, tpr.Spec.OpenstackInfo.Domain)
	if err := op.Clients.Openstack.DeleteUser(tpr.Spec.OpenstackInfo.Username, tpr.Spec.OpenstackInfo.Domain); err != nil {
	return err
	}

Ok, cool. Though:

For the deseeding to work the cluster TPR must not be deleted using kubectl. I can only imagine this has happened here. Lets leave this open for now and see if this keeps happening again.

Those klusters have all been deleted via Elektra.

I've cleaned up all service users in staging that were not correctly removed when the cluster was deleted.
