* application.properties support for spring.jms and spring.activemq
* more tests to verify ActiveMQConnectionFactory pooling
* Groovy support and simple sample with activemq
* Groovy detection mechanism is @EnableJmsMessaging annotation
* Add ability to detect spring-jms on the path and create a JmsTemplate with
ActiveMQConnectionFactory
* Create tests showing autoconfigured JmsTemplate with ActiveMQ, but prove it
backs off if a separate ConnectionFactory exists.
* Add support to spring-boot-cli to that it detects JmsTemplate, DefaultMessageListenerContainer,
or SimpleMessageListenerContainer, and turns on autoconfiguration as well as
add proper @Grab's and import statements.
* Write a jms.groovy test showing proper CLI support
