Disabling load-balancer doesn't remove the metallb-system namespace

[gabrielcocenza]

Summary

I've observed that once the load-balancer is set to true, setting to false it doesn't remove the resources that were deployed in the metallb-system

What Should Happen Instead?

As a user I would expect to have the metallb-system ns and resources deleted from the cluster if I run a command like:

sudo k8s set load-balancer.l2-mode=false

Reproduction Steps

1. sudo snap install k8s --classic --channel=1.33-classic/stable
2. sudo k8s bootstrap
3. sudo k8s set load-balancer.l2-mode=true . Wait a little bit and the metallb-system ns will appear
4. sudo k8s set load-balancer.l2-mode=false. metallb-system ns still present in the cluster

System information

• k8s on channel 1.33-classic/stable
• Ubuntu 24.04
