packaging command for rpm based distros

[Daniele Branchini]

Creating a package in a rpm-based distro from the setup.py is pretty straightforward and could be mentioned somewhere in the wiki:

python3 setup.py bdist_rpm --requires="python3-inotify python3-markdown python3-docutils python3-jinja2 python3-pytz python3-dateutil python3-pyyaml python3-pillow"
