Issues with Network Management and user management in menu (#1036)

* A problem with default values treatment at superusers (and users) on the main menu

* Solving issues when changing the selection of nic, ask_to_configure_network failed in several places.
Solved, temporarily with the creation of __getitem__ and get methods at NetworkManager

* Accept old style definitions for nic

* flake8 complains

* log string corrected (issue 1039)

* Correct exit when no disk is selected and we don't wish to continue
