[9.0] DISET version of the TokenManager service

[atsareg]

The DISET version of the TokenManager service is added. This will help to eventually get rid of all the Tornado services.

Why not put this into 8.0? The TokenManager is the only tornado service I have

[fstagni]

For each and every service for which we have the DIPS and HTTPs version, we have 2 files:

• a "NameOfHandler.py". This contains

  
  class NameOfHandlerMixin:
  # logic end "export_"s here

class NameOfHandler(NotificationHandlerMixin, RequestHandler): pass

- a "TornadoNameOfHandler.py". This contains
```python
class TornadoNameOfHandler(NotificationHandlerMixin, TornadoService):
    pass

which should be respected also here. So, at a minimum you need to modify accordingly also the "TornadoTokenManagerHandler.py". Or, at the 2 VERY different one from the other?

BTW I think this should also go to v8.
