Hey!

This pull request try to simplify packaging and building by using PBR and reduce
the necessary python code to generate a new releases.

In parallel this PR fix issue #18 (https://pagure.io/python-daemon/issue/18)

In second time we want to propose to add:
- pep 8 checks by introducing flake8 in tox
- AST (Abstract Syntax Trees) security checks by introducing bandit with tox

Summary

• Modernize the packaging by using PBR and setuptools;
• Introducing metadata inside setup.cfg;
• Using tox;
• Unittest on python 3.5, 3.6, 3.7;
• Remove module version;
• Remove toml file (pyproject.toml);
• Using PEP 516 (Build system abstraction for pip/conda etc) instead of PEP 518 (Specifying Minimum Build System Requirements for Python Projects);
• Introducing requirements files.

How to test it

$ git clone https://pagure.io/fork/hberaud/python-daemon -b refactor-packaging
$ pip install pbr
$ tox # test your unit tests
$ # pbr use git tag to generate release number
$ # you can generate a fake tag to test with it
$ git tag 3.0.0 # generate fake tag
$ python setup.py build # test packaging
$ python setup.py sdist # test packaging
