feat(suse): support packaged installations

- add all components available in the default openSUSE Leap (OSS)
  repository to osfamilymap
- introduce global manage_user_group toggle to prevent the formula from
  changing users and groups managed by system packages
- allow configuration file override using
  pkg:component:<component>:config_file
