Customize concurrency at listener level

Browse Source 
Prior to this commit, customizing the concurrency to use fo a given JMS
listener involved to define it in a specific listener-container. As
this is quite restrictive, users may stop using the XML namespace
support altogether to fallback on regular abstract bean definition for
the container.

This commit adds a concurrency attribute to the jms and jca listener
element as well as on the @JmsListener annotation. If the value is set,
it takes precedence; otherwise the value provided by the factory is
used.
