Fix for Make iptables and ipvs modes of kube-proxy MASQUERADE --random-fully if possible

#k8s #solved

Solution Summary

Source Network Address Translation (SNAT) port collisions can cause network degradation in Kubernetes. The resolution, provided in PR #78547, configures the iptables and IPVS modes of kube-proxy to use the --random-fully flag for masquerading. This forces fully randomized source port selection, mitigating collision risks and preventing intermittent connection drops.
