feat: adding reposync wrapper and tooling

- add autosyncer/autopromoter scripts
- add timer and service to initial sync process
- add timer/service for daily/weekly/monthly autopromote
- add define to manage each repo
- add nginx webserver to share repos
- add favion.ico if enabled
- add selinux management, and packages for selinux
- cleanup package management, sorting package groups into package classes
