Bootstrapper should check if user has appropriate permissions and if not create cluster role

[jlewi]

See #105 and RBAC Issue

As part of cluster preparation we should check whether user has necessary permission to create Kubeflow components (e.g. the role bindings) using the auth API. If not we should see if we can create a cluster role binding making the user a cluster admin so they will be able to deploy Kubeflow.
