While these changes look appropriate for achieving the stated goal, have you considered either updating this module to use a more recent RHEL version than RHEL 7 or, better yet, parametrizing it for all supported RHEL versions? RHEL 7 is now out of maintenance support and is in its extended life cycle support phase.

I won't consider this a blocking question, and I don't want to pick on you specifically, @vijaysawant, since I know this pattern is common throughout the Robottelo codebase. However, I think it would be good to take opportunities move away from it when we encounter them.
