Switch to refstack-client binary and some cleanup

* Use latest pbr >= 2.0.0
* Removed gitpython as it is not used within the code
* switched to refstack-client binary in README.rst
* Removed unwanted stuff from setup.py as those are already in setup.cfg
* use pip install -e . to auto install dependencies from requirements.txt
  as well as package.
