XD-1970 Improve Thread Naming for Rabbit Bus

JIRA: https://jira.spring.io/browse/XD-1970

Previously, all listener container threads in the
RabbitMessageBus had the same name.

Use the queue name as the thread prefix so that you
can easily identify the module in the log.
Fixed compile warnings
XD-1870 More Rabbit Host/Port -> Addresses
