Refactor: tried to refactor code

- move scripts to assets/scripts (and updated build)
 - put most logic into HaproxyConfigGenerator
 - created DockerLabelHandler for all label handling from previous code
 - added unit tests and fixtures to cover HaproxyConfigGenerator and DockerLabelHandler
 - added a Makefile with build (for docker build) and test targets

assets/scripts/static.py
