Single argument to disable autoconfiguration

[murinicanor]

hi,

i'm new to ansible, so maybe i'm using it wrong, but it would be great if there were one variable that states, that debops.ifupdown should not do any default configuration. at the moment i can disable the default interface layout by setting ifupdown__interface_layout to manual, but i also have to set ifupdown__ethernet_interfaces to {} to disable the creation of interface files for any of my physical adapters. it would be great if there was only one knob for turning off all autoconfiguration.

thanks for your work!
