use pbr fully for easier package building

Even though we always had pbr has a dependency, we didn't use it to
its full extent to ease the building the process.

- use the automatically generated AUTHORS and ChangeLog files when we
  do a `python setup.py bdist_wheel`.

- use pbr postversioning to get the synergy-service package version
  (see: http://docs.openstack.org/developer/pbr/#version)
