Elena Ezhova 856a653cbf Remove usage of global CONF
Change the API of oslo.service to accept conf object and
remove usage of global CONF object throughout the library.

List of functions/classes that accept conf as a parameter:
  1. eventlet_backdoor.py
    * initialize_if_enabled
  2. periodic_task.py
    * PeriodicTasks
  3. service.py
    * launch
    * ServiceLauncher
    * ProcessLauncher
  4. sslutils.py
    * is_enabled
    * wrap

Fixed the unit tests.
