Fix detect vxlan parent IP logic not skip IP addresses with a full subnet mask (e.g., /32 for IPv4 and /128 for IPv6).
On AWS, when main network card has multiple IP, and it is set to default route.

if ones == 32 && bits == 32 || ones == 128 && bits == 128 {
        continue
}

iptables

Add more iptabels accept rule skip cilium rule.

EgressClusterInfo

Add kube-controller-manager labels case, We use these labels to retrieve the kube-controller-manager Pod arguments in order to obtain the cluster CIDR. Since different clusters have different kube-controller-manager labels, the content of the labels also varies.

If not found CalicoIPPool CRD in current cluster, skipping watch CalicoIPPool.
