Add option to configure the Message ID Type

We need to set a messageId to UUID format on messages we send. When I look at the source code in https://github.com/apache/qpid-jms/blob/master/qpid-jms-client/src/main/java/org/apache/qpid/jms/JmsSession.java I see that the message id is generated using the producer id and a sequence number. (Line 923).

Is it not possible to use UUID:s as message ids?
