3.0.1 policy-handler - cleaning sonar smells

- no change of functionality or API
- removed the unused enum34>=1.1.6 from requirements.txt and setup.py
- refactored run_policy.sh to redirect the stdout+stderr only once
- refactoring to remove smells+vulnerability reported by sonar
  -- renamed Config.config to Config.settings
  -- removed the commented out code in customizer.py
  -- renamed StepTimer.NEXT to StepTimer.STATE_NEXT to avoid the
     naming confusion with the method StepTimer.next.
     Also renamed the related StepTimer.STATE_* constants
  -- refactored several functions by extracting methods to eliminate
     4 out of 5 "brain-overload" smells reported by sonar
  -- moved the literal string for the socket_host "0.0.0.0" to a
     constant on the web-server to avoid the reported vulnerability
