Allocation for services done

- Allocation for services done
first of all - dummy pricing object is unique per service AND ENVIRONMENT

second of all - what if dummy pricint object was not created for this Service? 
it's better to get it like this:
```
service_environment = ServiceEnvironment.objects.get(service__name=kwargs.get('service'), environment__name=kwargs.get('environment'))
pricing_object = service_environment.dummy_pricing_object
