This reverts commit e375678674.
The workaround of explicitly specifying root for the kubelet unit was
for pulling images from private registry. Kubernetes now have a
dedicated mechanism with imagePullSecret.
* Add restart for weave service unit
* Reuse docker_bin_dir everythere
* Limit systemd managed docker containers by CPU/RAM. Do not configure native
systemd limits due to the lack of consensus in the kernel community
requires out-of-tree kernel patches.

Also place in global vars and do not repeat the kube_*_config_dir
and kube_namespace vars for better code maintainability and UX.

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.
* Add for docker system units:
ExecReload=/bin/kill -s HUP $MAINPID
Delegate=yes
KillMode=process.
* Add missed DOCKER_OPTIONS for calico/weave docker systemd unit.
* Change Requires= to a less strict and non-faily Wants=, add missing
Wants= for After=.
* Align wants/after in a wat if Wants=foo, After= has foo as well.
* Make wants/after docker.service to ask for the docker.socket as well.
* Move "docker rm -f" commands from ExecStartPre= to ExecStopPost=.
hooks to ensure non-destructive start attempts issued by Wants=.

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.
Currently kubespray does not install kubernetes in a way that allows cinder volumes to be used. This commit provides the necessary cloud configuration file and configures kubelet and kube-apiserver to use it.
