Add a configuration property for configuring sessionTransacted flag on auto-configured JMS listener container

[vpavic]

This commit introduces spring.jms.listener.session-transacted property in order to enable explicit configuration of sessionTransacted on the DefaultMessageListenerContainer.

Prior to this commit, sessionTransacted would be configured implicitly based on presence of JtaTransactionManager.

---

The background for this change is that some JMS providers (SQS in my case) do not support transactions (see related code). With such a provider, the default behavior of auto-configuration to set sessionTransacted to true when JtaTransactionManager is not present results in a non-working setup that requires something along these lines:

@Bean
DefaultJmsListenerContainerFactory jmsListenerContainerFactory(ConnectionFactory connectionFactory,
        DefaultJmsListenerContainerFactoryConfigurer configurer) {
    DefaultJmsListenerContainerFactory jmsListenerContainerFactory = new DefaultJmsListenerContainerFactory();
    configurer.configure(jmsListenerContainerFactory, connectionFactory);
    jmsListenerContainerFactory.setSessionTransacted(false);
    return jmsListenerContainerFactory;
}

Note that this PR does not change the existing logic - if spring.jms.listener.session-transacted is not set, sessionTransacted will still be set based on presence of JtaTransactionManager.
