TMN — Issue: create and delete are always confirmed

Summary: This is an issue for the "CORBA/TMN Interworking RTF":

In the OSI Facilities, the specification potentially allows to have
unconfirmed ManagedObject creations/deletions, whereas in Q3/OSI they
are always confirmed. The OSI Facilities should thus explicitly say that
for creation and deletion operations, LinkedReplyHandler and
EndOfRepliesHandler cannot be null object references, otherwise an
exception should be raised (e.g. BAD_PARAM).
