With the addition of modules.d/99squash module, most of the files in
the initramfs image can now be squash'ed. While this saves space, this
can also be extended further to provide support for having different
initramfs images built into a single image, each squash'ed separately
& activated based on different boot scenarios.
For that, introduce two dracut options. One, '--squash-input-images':
takes a space-separated list of input initramfs images to squash &
include in the initramfs image. Patch one adds this option.
Two, '--squash-image-conditional': takes a script file that sets up
the appropriate squash image for every possible boot scenario. The
second patch introduces this option.
