Update for ConnMan 0.79 API changes

* Use Manager.GetServices method instead of Manager.Services property
* Use Manager.GetTechnologies / Technology.Powered instead of
  Manager.EnabledTechnologies method
* Use Technology.Powered property instead of Manager.EnableTechnology
  and Manager.DisableTechnology methods
* Use Technology.Scan method instead of Manager.RequestScan method
* Listen for ServicesAdded, ServicesRemoved, TechnologyAdded and
  TechnologyRemoved signals instead of monitoring the old Services
  and EnabledTechnologies properties

Also remove unused code relating to the old API.
