OCPBUGS-78694: backport: openstack: Disable LoadBalancer in cloud config when Octavia is unavailable

[eshulman2]

When Octavia (load-balancer) endpoint is not available in the OpenStack service catalog, explicitly set [LoadBalancer] enabled = false in the cloud provider config. This prevents the Cloud Controller Manager from crashing on startup due to an upstream change in cloud-provider-openstack that changed error handling from klog.Errorf to klog.Fatalf when the LoadBalancer client cannot be created.

The fix uses the same pattern already established in the cluster destroy code (pkg/destroy/openstack/openstack.go) to detect Octavia availability by checking for gophercloud.ErrEndpointNotFound.
