Shorten deployment time with:
- Remove redundand roles if duplicated by a dependency and vice versa
- When a member of k8s-cluster, always install docker as a dependency
of the etcd role and drop the docker role from cluster.yaml.
- Drop etcd and node role dependencies from master role as they are
covered by the node role in k8s-cluster group as well. Copy defaults
for master from node role.
- Decouple master, node, secrets roles handlers and vars to be used w/o
cross references.

Nearly the last stage of source all components to containers.
Kubectl will be called from hyperkube image.
Remaining tasks:
* Move kube_version variable to kubernetes/preinstall
* Drop placeholder download.nothing requirement
kubelet via docker
kube-apiserver as a static pod
Fixed etcd service start to be more tolerant of slow start.
Workaround for kube_version to stay in download role, but not
download an files by creating a new "nothing" download entry.
This should make things a little more composable,
by making these roles meta roles that perform no
actions by default we allow each role to own its own
resources.
