The current implementation when Etcd TLS was added does not support using calico as the configuration and client certificates are not present. This PR updates the calico manifests and adds the distribution of the client certificate
Renamed the k8s-1.8 manifest to a k8s-1.7. This is required because of config
change that occurs between k8s 1.6 and k8s 1.7. This refactor will also
be re-used when Calico Kubernetes data source support is added to kops.
Updated bootstrapchannelbuilder with the new Calico version numbers.
