Add a new --internal-cidr flag that allows users to specify which CIDRs should be considered during internal IP auto-detection. This flag can be specified multiple times to allow multiple CIDRs. When set, only IPs within these CIDRs will be selected as the internal IP, preventing incorrect IP selection (e.g., when CiliumInternalIP is chosen over the real node IP due to lexicographic sorting). Example usage: --internal-cidr=192.168.0.0/16 --internal-cidr=$(NODE_IP)/32 Also update manifests for cilium and flannel deployments to use this flag with NODE_IP from Kubernetes Downward API.

Summary
Add a new
--internal-cidrflag that filters internal IP auto-detection by specified CIDRs. This flag can be specified multiple times.Motivation
When running Kilo with CNI plugins like Cilium, the auto-detected internal IP may incorrectly select overlay network IPs (e.g., 10.244.x.x) instead of actual node IPs (e.g., 192.168.x.x) due to lexicographic sorting in IP selection. This causes routing issues as
privIfacegets set to the wrong interface.Usage
