Fix etcd play to only run on non-k8s-cluster nodes

3 nodes, but none are standalone etcd roles.

Copy hyperkube cni plugins optionally for calico deployment

upstreaming to k8s

Fix init scripts for etcd. Fixes #383

OpenStack minor fix

Fix resolvconf executable discovery

If resolvconf was installed and then removed, the file
/etc/resolvconf/resolv.conf.d/head remains in the filesystem

- change discovery of 'resolvconf' executable to check if it
  can be located with 'which resolvconf' command or not.

Hyperkube from CoreOS now ships with all binaries required for
calico and flannel (but not weave). It simplifies deployment for
some network plugin scenarios to not download CNI images.

Improve systemd handling and stabilize docker

Add future docker versions

Fixes #390

Creating the unit using default settings early on
and then changing it during network_plugin section
leads to too many docker restarts and duplicated code.

Reversed Wants= dependence on docker.service so it does not
restart docker when reloading systemd

Consolidated all docker restart handlers.
