Brief Description
-----------------
I think this issue was introducer by https://opendev.org/starlingx/config/commit/65dfc46b9b0f08e9515970268c50fa5027d4c442.

On my system configuration there was no proxy present and the sysinv-utils script fails to treat this case. Moreover, the script returns 0 when it shouldn't and the playbook fails to catch the error.

    ]
}

Because the sysinv-utils script does not create the localhost_override_backup.yml file, the playbook generates an error later when a task tries to write to the yml file.
