Adding pull-secrets to the oc adm release info... command. (#164)

In order to access the release payload, we need to have access to the
pull-secret of the cluster.

In addition, since we are running in a "hub" cluster, `podman` cannot be
used, therefore, I have replaced it with an `oc run ...` command
instead.
