kubevirt.io demo doesn't indicate need to use system:admin for oc commands

[markllama]

The kubevirt.io try-me for minikube/minishift has oc commands that require use of the system/admin user. There is no note to that effect in the text.

Deploying KubeVirt on OpenShift Origin
On OpenShift Origin, the following SCCs need to be added prior kubevirt.yaml deployment:

$ oc adm policy add-scc-to-user privileged system:serviceaccount:kube-system:kubevirt-privileged
$ oc adm policy add-scc-to-user privileged system:serviceaccount:kube-system:kubevirt-controller
$ oc adm policy add-scc-to-user privileged system:serviceaccount:kube-system:kubevirt-apiserver

$ export VERSION=v0.8.0
$ oc apply -f https://github.com/kubevirt/kubevirt/releases/download/${VERSION}/kubevirt.yaml

Resolved for minikube and minishift. AWS and GCE images are still out of date.

addressed in #166 with an explicit login as system:admin prior to running the scc related commands although arguably, both oc and kubectl commands from the getting started require enough privileges for kubevirt deployment to actually happen
