rpm-ostree: Setup readonly sysroot for ostree & rw karg
- Enable read only sysroot in the ostree repo config. - Add `rw` to the kernel arguments to keep statefull parts of the system (/var & /etc) writable. - Update units tests to account for the new rw karg (cherry-picked from a commit 0e00c90) Related: RHEL-2250

Apply the bootloader options before the installation
Some of the bootloader options are not needed until the installation. If we apply them during the scheduling of the partitions, it won't be possible to change them after that, for example, from an add-on. Let's apply these options later, right before the bootloader installation. (cherry-picked from a commit dbac59a) Related: RHEL-17205

bootloader: Remove the install_boot_loader function
Move the implementation to the `InstallBootloaderTask` class. (cherry-picked from a commit e96bded) Related: RHEL-17205
-
bootloader: Add the collect_arguments method
Add a new method for collecting kernel arguments for the installation. (cherry-picked from a commit 6967994) Related: RHEL-17205

bootloader: Create an installation task for collecting kernel arguments
Use the `CollectKernelArgumentsTask` task to collect kernel arguments for the installation. It will be used by the bootupd support that needs to be able to collect kernel arguments without installing the bootloader. (cherry-picked from a commit 8a7641e) Related: RHEL-17205

ostree: Use bootupd if installed by payload
Original commit message from Colin Walters was: The https://github.com/coreos/bootupd project was created to fill the gap in bootloader management for ostree-based systems. When it was created, it was just integrated into Fedora CoreOS and derivatives; this left the Atomic Desktops (Silverblue etc.) as unfixed, and it was never used by RHEL for Edge. This PR is aiming to circle back and close that gap. We detect if bootupd is in the target root; if it is, then we skip the regular bootloader work, and just run bootupd to perform the installation. The other hacks we have around the grub config are no longer necessary in this mode. (cherry-picked from a commit 8e690d5) Resolves: RHEL-17205

bootloader: Detect bootupd and skip regular install

This is an even newer behavior that takes over handling of the "UUID stamp files", which we want in general instead of using the static labels. Note `--write-uuid` implies `--with-static-configs`. This should fix this use case: ``` clearpart --all --initlabel --disklabel=gpt reqpart --add-boot part / --grow --fstype xfs ``` Whereas right now we require: ``` clearpart --all --initlabel --disklabel=gpt reqpart part /boot --size=1000 --fstype=ext4 --label=boot part / --grow --fstype xfs ``` Specifically the `--label=boot`.
