DNS Controller Optional
The current implementation enforces a dns-controller is running; given the user can switch the make the kube-apiserver server Internal and then reuse the dns for the masterInternalName; this effectlively removes the need to run the service (assuming your not using it for pods, node and service dns)
- adding a disableDnsController to the ExternalDNS spec provides a toggle on the addon (name is definitely up for debate)
- the default behaviour remains, the dns-controller is always pushed as an addon
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.

* 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.

Add Cloud Controller Manager addon
This adds the CCM addon for the Kubernetes cluster.
This is a follow-up PR to https://github.com/kubernetes/kops/pull/3408.

including a Weave Net template for Kubernetes 1.7 and above which adds
a volume-mount for the iptables lock file, which avoids collisions
between Weave components and kube-proxy that would result in a
half-configured Weave network.
This is only for version 1.7 and above because it requires the change
in https://github.com/kubernetes/kubernetes/issues/47212

Add external-dns as addon.
This superseeds route53mapper as it has multicloud support documentation and YAML taken from https://github.com/kubernetes-incubator/external-dns

Support for using hostPort when using calico
For enabling hostPort we need to turn on portmap cni plugin.
In this PR I updated calico and calico-cni images to latest version which already includes the portmap binary, and then I only needed to modify the cni config file to enable it and change its extension from .conf to .conflist.
This is related to:
https://github.com/kubernetes/kops/issues/3132
I think we should do the same for kube-router, flannel and weave (are there any other cni plugin supported by kops?)
In PR [#2635](https://github.com/kubernetes/kops/pull/2635) the version
of calico was updated as part of canal. What this PR missed was bumping
the version of the addon. This meant that if you upgraded a kops
cluster from v1.6.0 to v1.6.1 the new version of calico was not picked
up because `channels apply` does not think the daemonset needs to be
updated.
Currently, we are using .NonMasqueradeCIDR in the wrong fashion. We
should be using .KubeControllerManager.ClusterCIDR to prevent IP
collision with Service IPs.
