Barcode scanners are now part of KeyboardUSBDriver. We also add
the possibility to change the keyboard/scanner layout from an
action. The list of available layout can be retrieved with a new
route.
`hw_scanner` has been removed. Backward compatibility is ensured
because the name of the route that is now used in community is the
same that was used previously.
