Subject: QPID-2575 : Add getClientID to SessionModel and standardise use
 accross 0-8/0-10, 0-10 does not appear to provide a client ID so maintaining
 use of Principal Name. This means migration between 0-8 and 0-10 will not
 behave as expected. Correct erroneous usages of session.getPrincipal when
 comparing with queue.getOwner is requried. Queue owners are the client id not
 the authenticated user.
