[authentication] Add RadiusToken about django-freeradius

[Vivekrajput20]

Hi Fed
I have doubts regarding what we want to achieve here.
Currently we are using rest framework token model to authorize in freeradius and then the same token model is used in openwisp radius for the authentication. Now what we want to do is to keep using the rest framework token model for authorization in free radius and create a Radius token model that will inherit rest framework token model and use this model in the openwisp for authentication purpose.
Is that what we want?
Thanks
Vivek

If there's an abstract model in DRF we can inherit from then yes, otherwise we can make a new one.
