Changes from previous (RHEL 9.0 Beta):
- Edge container: Switched to nginx from apache. Change in pipeline and
package sets.
- All bootable x86_64: Packages for hybrid boot added (efibootmgr).
- Edge commit and edge container no longer require explicitly enabling
greenboot services.
All three "distros" share the same code for now. Adding manifests to
track changes before updating the RHEL 9.0 GA definitions.
