Service Provider Status (ISSUE-137)

Some possible status ambiguities for service providers.  All are solvable with trivial engineering. 

-If a service provider is using its own domain:
-Is the entity a first party, third party, or service provider?
-Which party is it providing outsourcing services to?  (Might be multiple parties in different roles.)
-If a service provider is using a different party's domain (e.g. a CNAMEd analytics service):
-Who is the service provider?
