Bug-fix: Remove flows from voltha for deleted subscriber, even if sadis cannot
fetch information about the deleted subscriber.

Other changes:
      - Added a cli command that details subscribers that have actually been programmed in the data plane
      - Changed all cli commands to start with volt-* as all app cli commands should
      - removed DeviceIdCompleter from the 'olts' cli command as it is not needed
      - removed unused method, renamed another one, fixed some logs
      - S-tags are no longer 'DeviceVlans', so changed variable name
