Queue message counts

QueueExplorer displays a message count next to a queue name. In addition to Azure Service Bus “active message count” which is always visible, additional counts will be displayed if not empty:

• D: - Deadletter messages
• S: - Scheduled messages
• T: - Transfer messages
• TD: - Transfer deadletter messages

Example:

`orders(5, D:3, S:1)` - there are 5 active messages, 3 in deadletter queue, and 1 scheduled message.
