Add support for devince binding

In some cases we need to use block devices directly (Physical volume storage). This new variable allows the user to mount devices with the --device option for flatcar baremetal. How to use : add a list of objects like this to the cluster definition : worker_bind_devices = [ { source = "/dev/sdb" target = "/dev/sdb" }, { source = "/dev/sdc" target = "/dev/sdd" }, { source = "/dev/sdd" target = "/dev/sdd" } ] This will bind the source device on the target directory in evry node.
