- Simplified the label matching logic in the Flannel discovery to use `controllerClient.MatchingLabels`. - Updated Canal discovery to pass `metav1.NamespaceSystem` directly to `extractCIDRsFromFlannelConfigMap`, eliminating the need to extract the namespace from the first DaemonSet.

What would you like to be added:
I would like to request an enhancement to the Flannel CNI discovery logic to list DaemonSets in all namespaces and filter them by the
k8s-app=flannellabel.Why is this needed:
The current Flannel discovery implementation may not capture all Flannel instances if they are deployed in different namespaces. By updating the discovery code to search across all namespaces, we can ensure that all Flannel DaemonSets are recognized and accounted for, improving network connectivity and resource management in multi-namespace Kubernetes environments. This change would enhance the reliability of the Flannel network configuration and make it easier to manage Flannel deployments.
