* Limit each CNI provider to 100m
* Remove CPU limits - they cause serious problems
(https://github.com/kubernetes/kubernetes/issues/51135), but this also
makes the CPU allocation less problematic.
* Bump versions and start introducing the `-kops.1` suffix preemptively.
* Upgrade flannel to 0.9.0 as it fixes a lot.
Kube-router was using --cluster-cidr flag to get the subnet allocated
for pod CIDR's. But now kube-router has the ability internally to infer
the CIDR allocated for the pod's by getting the information from
kubernetes API server node spec's
fixes#2606
Most part of the changes are similar to current supported CNI networking
provider. Kube-router also support IPVS bassed service proxy which can
be used as replacement for kube-proxy. So the manifest for kube-router
included with this patch enables kube-router to provide pod-to-pod
networking, IPVS based service proxy and ingress pod firewall.
