JIRA: https://jira.spring.io/browse/INT-3941
Previously, like the SF `<jms:/>` namespace, Spring Integration used a default bean
name `connectionFactory` for the JMS Connection Factory.
Spring Boot auto-configures a bean name `jmsConnectionFactory`.
Since it is still common to use Spring Integration XML configuration with Spring Boot,
it is useful to align the two so that an SI app can use the auto configured bean.
