Expose @JmsListener endpoint id to annotation-derived listener container (for transaction definition name)

[zerocode]

Transaction name is always null when debug logging @Transactional`` @JmsListener methods.

This chunk of code in AbstractPollingMessageListenerContainer returns null for getBeanName():

                                // Use bean name as default transaction name.
                                if (this.transactionDefinition.getName() == null) {
                                                String beanName = getBeanName();
                                                if (beanName != null) {
                                                                this.transactionDefinition.setName(beanName);
                                                }
                                }

It should be easy to support by setting the beanName from the endpoint passed into createListenerContainer(JmsListenerEndpoint endpoint) { ... } in AbstractJmsListenerContainerFactory.

As a side note, exposing the endpoint id also enables the listener container to use specific thread names based on that id, just like the bean name for a manually defined listener container is also showing up in the thread names (with the default task executor).
