Manual system_images assignment in rke's cluster config
is dropped as for any particular kubernetes release Rancher
project holds a predefined, static map connecting Rancher's
Kubernetes version with particular system images, so it's
enough to define k8s version.

Kubelet can be configured on startup now - just add new key/values in:
kubelet-static-config.yml.j2
Also kubelet static (startup) configuration can be overriden later
(dynamically) during its runtime - for more info read this:
https://kubernetes.io/docs/tasks/administer-cluster/reconfigure-kubelet/

This commit updates rke (implementing K8S 1.15.4), kubectl binary and
helm binary with tiller image:
rke 0.3.0
kubernetes 1.15.4
kubectl 1.15.4
helm 2.14.2
dashboard 2.0.0-beta4
Kubernetes dashboard is also updated to be compliant with the 1.15 K8S.
Note 1:
There is a new datalist to split rke only images from other K8S related
images.
Note 2:
El Alto recommendation cannot be fullfilled to the letter, because rke
does not have any release supporting 1.15.2 version of kubernetes (only
experimental).

Plus the option to have etcd on tmpfs (volatile storage) for little
bigger (maybe) speed (NOT FOR PRODUCTION DEPLOYMENT!).

Adding binaries preparation into installation steps as rke binary need
to be renamed and helm binary need to be unarchived. Removing those
previously manual steps from BuilGuide

Either run kubectl proxy, but you must setup routes or kubectl on some
node (only infra has kubectl by default). Another option is connecting
onto the node where the dashboard is exposed via NodePort. Instructions
are here:

(1.7.X and above)

the kubeconfig is copied from the cluster config directory to ~/.kube/config.
Also, the playbook runs kubectl and helm roles to install tools.

Added a new playbook rke.yml and role rke which uses rancher RKE:
https://github.com/rancher/rke
It's an implementation of the kubernetes from rancher.com folks
and it is an alternative to the official kubernetes tool: kubeadm.
NOTE: Rancher has a notion of a 'control plane' which cannot run with
etcd on all nodes in a multi-node setup. Control-plane node is the
first kubernetes node from the inventory (as of now).
