[Documentation] load-balancer-enabled seems to only work with MetalLB

[mostafaCamel]

Bug Description

I integrated (via Helm) an OCCM on a k8s cluster and I created a loadbalancer. I thought I could use load-balancer-cidrs and load-balancer-enabled to specify a specific ip to use for the loadbalancer.

However, these configs seem to force the use of metallb

To Reproduce

-Deploy a k8s charm with load-balancer-enabled and load-balancer-cidrs unset

• Integrate with OCCM
• Set load-abalncer-cidrs and load-balancer-enabled
• You will notice a new metallb-system namepsace created
• Create a loadbalancer (could be traefik's in cos-lite)
• Describe the created service. You will see that is a metallb

Environment

Charmed Yoga. 1.32 k8s cluster (via the k8s charm) on top (the nodes are openstack VMs) then integrate OCCM (2.32) via Helm
