Strip down the playbook a little

[gswallow]

Howdy, nice playbook.

I forked it and stripped down the answer file a bit, eliminated the need for the network settings during foreman-install since I don't plan on using satellite server to manage DNS, DHCP, and TFTP. I think those tasks can be handled purely with hammer cli commands after installation? Or, at least there is documentation on how to add network management features post-install.

Would these changes interest you?

Thanks!
