Implement basic packaging/install/entry scripts

The packaging script will create a new tar.bz2 archive containing an install
script, a set of docker images, and a root folder with files to be installed.
The root folder includes a systemd service, a docker compose file, an entry
script, and a template config file.

On installation docker images are loaded onto the target system, install files
are copied, then systemd services are installed.
