Summary: Non-Durable Consumer Message Count

Initial Comment:
At the moment there is no way of determining the 
number of pending messages for a non-durable 
subscriber.

It would be helpful to have such capability in the admin 
interface.

Unlike queues, topics only hold messages for consumers that are 
active. A topic consumer only sees the messages that were 
published on or after the time that the consumer was created.

It is therefore not possible to determine how many messages are 
pending with having an instance of a TopicSubscriber (or durable 
subscription name).

To support non-durable subscribers, a method would need to be 
added to JmsAdminServerIfc along the lines of:
  int getMessageCount(MessageConsumer consumer);
