Deprecate spring.rabbitmq.template.queue in favor of spring.rabbitmq.template.default-receive-queue

[snicoll]

The latest Spring AMQP release has deprecated setQueue in favour of setDefaultReceiveQueue. We should probably adapt our configuration structure to match that change and deprecate spring.rabbitmq.template.queue in favour of spring.rabbitmq.template.default-receive-queue.

Given this change was introduced early in 2.1.x I am tempted to make it for 2.1.1 still.

Let's see what the rest of the team thinks.

Agreed on doing this for 2.1.1. The change described here as well as updating the test that's currently failing was what I was alluding to in #15271 (comment).
