[PATCH container 1/1] Optional mapped devices at vm boot

[moddingfox]

From: Tyst Marin <moddingfox at foxtek.us>

This change intends to add support for optional mapped usb devices.
Currently if a mapped device is unplugged vm boot will fail, tihs will provide an option to ignore specified missing devices.
This keeps the default behavior while allowing for optional devices to be specified.
