Create Debian package for sbws

We agreed that to easy bandwidth authorities to run sbws we should have a Debian package. This is also part of #17275 (moved). This ticket follows the issue created in github [0]

Tasks to have a Debian package:

• create a proper Python package (solved by GHXX, GHXX, GHXX)
• create metadata for the Python package, useful for source and binary distributions (solved by GHXX)
• create Debian ITP [1] (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=903976)
• try to get a team to collectively maintain the package so that it does not depend on a single person (https://alioth-lists.debian.net/pipermail/pkg-privacy-maintainers/Week-of-Mon-20180716/002184.html)
• get steam to release new version, currently blocked by #26848 (moved)
• (optionall) provide sbws releases via dist.tpo (#26849 (moved)) so that watch does not use Github
• create debian source package in Debian repositories (https://salsa.debian.org/pkg-privacy-team/sbws/)
• get the source reviewed
• get the package uploaded to Debian archive (sid)
• create debian backport to current stable (stretch)
• get backport reviewed
• get backport uploaded to Debian archive
• (optional) upload the package to deb.tpo
• (optional) create bug in Ubuntu to get the package distributed in Ubuntu too
