Consider Syncope domain for EE REST operations
The {{ChoreographyApi}} REST interface is missing, in its methods' parameters, the information about the Syncope domain (e.g. the tenant) making requests, or to be contacted back during {{notifyCompletion()}}.
I have also found, in the {{Choreography}} class from the chorSpec library, a 'tenant' field, which is probably supposed to carry out such information.
However, as we recently found for the choreography name, the tenant should become an additional parameter (possibly in the HTTP header) for all endpoints defined in the {{ChoreographyApi}} whose implementation will eventually call back Syncope for the {{notifyCompletion()}}, otherwise Syncope won't be able to recognize the domain for which perform its internal operations.
