nmcli integration

[smcgrat]

Thanks for this project guy's, looks very interesting, keep up the good work.

Suggestion for enhancement.

Feel free to ignore this if it is a result of my own environment.

The image I was testing with did not have Network Manager installed. Here's the patch roles/pre_ohpc/tasks/main.yml I generated to integrate it.
