initramfs-framework: module to support boot live image
setup-live module is a new module being introduced to integrate the functionality of init-live.sh into new scriptlet named setup-live in order to support the live boot image. The udev-extraconf rdepends is being added to perform automounting. It gets to run before the rootfs and finish module. The setup-live scriplet include the changes for: - Create a conditional loop for the bootparam_root variable. If it is not set, then it will boot from ROOT_IMAGE. Else, it will boot normally which is not from removable media. - Gives a standard path to the original boot disk mount which can be used to. While /media/sda is a good guess, it isn't always right, nor is it a good assumption that only one boot disk is in the system. - The current rootfs module has no support for rootfs images, currently it only support for rootfs partitions for wic image. Therefore, there is a need to assign the rootfs image for live image.
