0ceb426cd5 fix(k3s): re-enable cloud controller manager 
Otherwise the first node will use kube-vip's IP as its InternalIP,
causing issues with Kube API certificate due to an incorrect IP.

K3s's CCM does more than I thought, it not only handles Klipper LB but
also sets node InternalIP/ExternalIP and clears the uninitialized taint.

9f0d389abc feat!: install Cilium 
Installed using Ansible instead of ArgoCD because Cilium replaces
the default CNI, so ArgoCD pod cannot be scheduled before Cilium
is installed.
