By default kubedns and dnsmasq scale when installed.
Dnsmasq is no longer a daemonset. It is now a deployment.
Kubedns is no longer a replicationcluster. It is now a deployment.
Minimum replicas is two (to enable rolling updates).
Reduced memory erquirements for dnsmasq and kubedns
The default version of Docker was switched to 1.13 in #1059. This
change also bumped ubuntu from installing docker-engine 1.13.0 to
1.13.1. This PR updates os families which had 1.13 defined, but
were using 1.13.0.
The impetus for this change is an issue running tiller 1.2.3 on
docker 1.13.0. See discussion [1][2].

Since inventory ships with kargo, the ability to change functionality
without having a dirty git index is nice. An example, we wish to change
is the version of docker deployed to our CentOS systems. Due to an issue
with tiller and docker 1.13, we wish to deploy docker 1.12. Since this
change does not belong in Kargo, we wish to locally override the docker
version, until the issue is sorted.
By default Calico blocks traffic from endpoints
to the host itself by using an iptables DROP
action. It could lead to a situation when service
has one alive endpoint, but pods which run on
the same node can not access it. Changed the action
to RETURN.
The Vagrantfile is setup to use flannel. The default network
was changed to Calico (#1031). However, the Vagrantfile was
not updated to reflect this. Ensuring the Vagrantfile remains
functional on master, until someone decides to make it work
with Calico.
Operator can specify any port for kube-api (6443 default) This helps in
case where some pods such as Ingress require 443 exclusively.

When a apiserver_loadbalancer_domain_name is added to the Openssl.conf
the counter gets not increased correctly. This didnt seem to have an
effect at the current kargo version.
