[Bug 2098659] [NEW] Please support hostonly mode with full portability

[Benjamin Drung]

Public bug reported:

In Ubuntu, initramfs-tools builds portable initrds by default. We want
that user can replace hardware (e.g. the graphics card, keyboard) and
still be able to boot. Taking a disk from one machine, plug it into a
different machine, and boot should work out of the box.

We currently use `--hostonly --hostonly-mode=sloppy` (see bug #2084809).

Upstream bug: https://github.com/dracut-ng/dracut-ng/issues/748

Proposed solution:

* Rename `hostonly_cmdline` to `include_cmdline`. Deprecate the former name.
* Introduce `mode="{generic|hostonly|strict}"` where generic matches `hostonly=no`, hostonly matches `hostonly=yes hostonly_mode=sloppy`, strict matches `hostonly=yes hostonly_mode=strict`
* Add `include_system_configs={yes|no}` to decouple this behavior the mode.
