Docker entrypoint script for creating RPM/DEB repository based on linux distribution where script is running

usage: create-repo.sh [-d|--directory output directory] [-l|--list input rpm/deb list directory] [-a|--additional-lists list1.list]
-h --help: Show this help
-d --directory: set path for repo directory in container
-l --list: set path where rpm or deb list is stored in container
-a --additional-list: add name of additional packages list
                      can be used multiple times for more additional lists
-p --packages-lists-path: set path for other additional packages lists

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