It is reasonable that elements may need to include additional kernel modules in a dracut ramdisk. This is done with the --add-drivers option to dracut, but previously the value passed was hard-coded. This change allows an element to put a file containing its desired drivers in a dracut-drivers.d directory, and the list there will be added to the list of drivers added. This functions in essentially the same way as the binary-deps.d directory that already exists for including additional executables in a ramdisk. Change-Id: Ie892b908d36c175a469f7cde7dd803ad4b1942b6

dracut-ramdisk
Build Dracut-based ramdisks
This is an alternative to the ramdisk element that uses Dracut to provide the base system functionality instead of Busybox.
For elements that need additional drivers in the ramdisk image, a dracut-drivers.d feature is included that works in a similar fashion to the binary-deps.d feature. The element needing to add drivers should create a dracut-drivers.d directory and populate it with a single file listing all of the kernel modules it needs added to the ramdisk. Comments are not supported in this file. Note that these modules must be installed in the chroot first.
By default, the virtio, virtio_net, and virtio_blk modules are included so that ramdisks are able to function properly in a virtualized environment.
