Docker entrypoint script for creating RPM/DEB repository based on container platform type

usage: create-repo.sh [OPTION]...

  -d | --directory              target repository path
  -l | --list                   input rpm/deb list directory
  -a | --additional-list        additional packages list; can be used multiple times
  -p | --packages-lists-path    other additional packages lists
  -r | --drop-cache             remove cached packages (use package cache by default)
  -h | --help                   show this help

Both paths have to be set with shared volume between
container and the host. Default path in container is: /tmp/
Repository will be created at: /<path>/resources/pkg/rhel/
RMP/DEB list is stored at: ./data_list/
