Provide more context for DoesNotExist Exception

With FastAPI it's possible to register a central exception handler for certain errors.
It's elegant to register a listener for DoesNotExist, because then the error handling doesn't have to be created in every route.
However I'd like to give a proper error message what kind of Model did not exist and with what primary key it was queried.
Currently that is not possible because DoesNotExist doesn't provide the required context.

Ideal implementation:

from tortoise.exceptions import DoesNotExist

 try:
    obj = await MyModel.get(id=1)
except DoesNotExist as e:
    assert e.model is MyModel
    assert e.pk_name == 'id'
    assert e.pk_value == 1

PS: It would be nice if we could rename DoesNotExist to DoesNotExistError

Start with the tortoise.exceptions.DoesNotExist entry point and trace the MyModel.get(id=1) lookup that raises it. Define completion by making the exception expose the model, primary-key name, and queried value as shown; the requested rename to DoesNotExistError is an additional consideration.
