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.

etcd facts are generated in kubernetes/preinstall, so etcd nodes need
to be evaluated first before the rest of the deployment.
Moved several directory facts from kubernetes/node to
kubernetes/preinstall because they are not backward dependent.
Running etcd in Docker reduces the number of individual file
downloads and services running on the host.
Note: etcd container v3.0.1 moves bindir to /usr/local/bin
Fixes: #298
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.
