Support multiple subnet definitions in CNI conf
What happened?
kube-router should support multiple subnet definitions in CNI conf. kube-router populated CIDR range from which host-local ipam allocated IP address for the pod. But 10-kube-router.conf filed with signle entry CIDR which was the only option supported in earlier CNI specification version. Though its still supported as of 0.8.0 cni version, we should fix in kube-router to support ranges to be future proof
What did you expect to happen?
{ "cniVersion": "0.3.0", "name": "mynet", "plugins": [ { "bridge": "kube-bridge", "ipam": { "subnet": "10.1.0.0/24", "type": "host-local" }, "isDefaultGateway": true, "mtu": 1480, "name": "kubernetes", "type": "bridge" } ] }
should be with ranges as in this example
