This commit entirely replaces NAT in Kilo with a few iproute2 rules. Previously, Kilo would source-NAT the majority of packets in order to avoid problems with strict source checks in cloud providers causing packets to be considered martians. This source-NAT-ing made it difficult to correctly apply Kuberenetes NetworkPolicies based on source IPs. This rewrite instead relies on a handful of iproute2 rules to ensure that packets get encapsulated in certain scenarios based on the source network and/or source interface. This has the benefit of avoiding extra iptables bloat as well as enabling better compatibility with NetworkPolicies. Signed-off-by: Lucas Servén Marín <lserven@gmail.com>
