oc-cluster: Fix to show deployment output in any case

[simonmeggle]

I think it is better to show the original output of the executed command instead of assuming that the command was not found, e.g.

--> Creating resources ...

    error: buildconfigs.build.openshift.io "origin-release-builder" already exists
