* Better comments in our Docker images
* Make `cli/access-permissions.sh` compatible with other Apache groups such as `http` for Linux Arch
* Better `/Docker/entrypoint.sh` supporting various Apache configuration paths (and slightly faster).
* Add test image for Linux Arch (not sure we will keep it)
