Admininistration functionality for [Simple|Direct]MessageListenerContainer via jmx

[rfelgent]

Hi @ALL,

at my company we have created code that exposes basic admininistration functionality for [Simple|Direct]MessageListenerContainer: the so called MessageListenerContainerAdmin.

The current feature set is compromised of:

• start|stop of listener containers for queue x
• setting concurrency like maxConsumer, minConsumer for queue x
• setting batch like batchSize, receiveTimeout for queue x

The idea of a MessageListenerContainerAdmin is highly inspired by AmqpAdmin.
My company would like to contribute such code to the core spring-amqp framework.

If you people (especially @garyrussell as lead developer of spring-amqp) are interested in this feature, I could make a PR.

Sure! Sounds good; thanks. I will create an issue from this discussion.
