Martin Kopec 0e085cdf85 Refactor to improve modularity, scalability, OOP
* each service class was moved to a new file
* Service and VersionedService were moved from api_discovery to service_base.py
* api_discovery.py is removed and methods for discovery were moved to a newly
  created class Services - class holds methods related to instantiating
  services, discovering their versions and extensions, configuring them
* constants were moved to an independent file - constants.py
