Edge and IoT manifests are modified from the new option handling. The
"parent" commit ID isn't specified in the options anymore, but it is
(fake) resolved by the manifest generator.
Of particular note is the iot-raw-image manifest that now properly uses
the commit ID in the copy stage for the firmware.
The resolved ostree commits are now stored in the content part of the
manifest metadata alongside package specs and containers.
Add a basic support for building RHEL-8.9 and RHEL-9.3 images with
composer.
Add 8.9 and 9.3 repositories to the multitude of places where we have
them.
Generate image test manifests for 8.9 and 9.3. No functional testing is
added for 8.9 or 9.3 at this moment.
This change unblocks the RHEL Gating (since unit tests are currently
failing on 8.9 and 9.3 as on unknown distribution).
