Actually, docker is used to test Linux packages once they are built.
The packaging process is done on the host system where package.py is
run.
Consequences:
* difficult to reproduce an exact same build on another host
* changing a Debian/Ubuntu target version means some upgrade steps
on the build host (mix that with the fact that the host also
could build old Odoo versions)
* Fedora rpm package is built on an Ubuntu system (which is not a
real problem but it could be)
With this commit, the package.py utility is refactored to use Docker
containers to build the Gnu/Linux packages.
Also, the Debian package is adapted for Debian Buster, the RPM package
is built based on Fedora 30.
Some minor changes are also made in the windows packaging system.

* Remove dependency on less-plugin-clean-css which distribution
packages are broken on debian stretch and derivated.
* Updated documentation.
* Lessc provides a `--compress` argument that could solve this issue.
According to the documentation at http://lesscss.org/usage/: "[...]
Compress using less built-in compression. This does an okay job but
does not utilise all the tricks of dedicated css compression[...]"
However, using this argument works on lessc 2.5.3 but not on 1.4.2
(`--compress` arg is present but seems to be break some rules
i haven't been able to put my finger on).
* Finally, use the minification of the StylesheetAsset that takes care
of removing the spaces, the comments and the sourcemap with regexes.
fixes issue #9113
