making SA privileged

[hupiper]

This is the error I get when I run the command from the README:

oc adm policy add-scc-to-user -z azure-build-sa privileged                                    [ruby-2.6.8p205]
Error from server (Forbidden): clusterrolebindings.rbac.authorization.k8s.io "system:openshift:scc:privileged" is forbidden: User "cluster-admin" cannot get resource "clusterrolebindings" in API group "rbac.authorization.k8s.io" at the cluster scope

This worked for me when I used a user with cluster-admin privileges, and we'll definitely need to take a look into this a bit more
