feat(systemd): Improve AlmaLinux OS and CloudLinux OS support (#5265)

AlmaLinux OS is binary compatible with RHEL
and CloudLinux OS based on AlmaLinux OS.

Use the same options with rhel on these systemd services:
- Cloud-init: Local Stage (pre-network): cloud-init-local.service
- Cloud-init: Network Stage: cloud-init.service
- Cloud-init: Final Stage: cloud-final.service
