RHEL 7 does not ship tgtadm or tgtd so they cannot be used in the deploy ramdisk. This change separates the tgt-specific parts of the ramdisk into their own element, and adds a new one that supports targetcli instead. For now, the tgt implementation can only be used with traditional busybox ramdisks and the targetcli one can only be used with dracut. This is because dracut is primarily used for RHEL right now so it makes sense to keep the dependencies simple. If there is a future desire to mix and match the implementations that could be done, but it would require users to explicitly select between tgt and targetcli.

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.
