initrd/bin/network-init-recovery: put usb tethering and ethernet activation in functions and ask user prior of using each mode
Also remove output of attempted module loading since DEBUG will show if needed Remove timeout after 30 seconds to unify UX and block Change UX wording Should address all PR review comments Signed-off-by: Thierry Laurion <insurgo@riseup.net>
