astakos: Record the service originating a resource

Add field service_origin in model Resource as well as in the
resource definitions, indicating the service where the resource
comes from. It is not a foreign key, in order to allow deleting
a component/service, without affecting registered resources and

API call /service_quotas uses this field to identify relevant
parent a80d4e96
