create setup.py or pyproject.toml and support system wide installation

[blshkv]

This is a common problem that many tools which we want to distribute do not support system wide installation. Some of these tools provide their own "install.sh" or "setup.sh" with a distro specific commands (sudo apt-install) to install dependencies instead of a proper setup.py/pyproject.toml (PEP 517).
With a proper setup.py script, an end user can install it using the following single command:
python3 setup.py install --user. It also a distro friendly and makes life for maintainers easier.

The end result, a FHS compliant directory structure should be created.
In case if software produce any output, a local user directory should be used, such as ~./<software>/

There are some custom cases (installing non-python packages, data files etc) which have been resolved in other packages. Bellow, are reference points on such bug reports with solutions (patches)
