Juan Cruz Viotti 71ee0a6cf7 Support drive option in os initialize
This allows the user to bypass the drive selection dialog.

This option can be used along with `--yes` to make the command
completely non-interactive. For example:

	$ resin os initialize rpi.img 'raspberry-pi' --drive /dev/disk2 --yes
