@diegolovison Updated as you requested, please review.

Please also advise whether we should update line 175 as follows:
from: ray_fn(openshift_server=openshift_server, openshift_token=openshift_token)
to: ray_fn()

Requested changed because of the project namespace

Checked the Asciidoc code and rendered output. A few minor suggestions made. Checked the code blocks in the rendered output for consistency.
