Make sure that RabbitMQ metrics are configured early
The ConnectionFactory can be used early in user configuration to configure an `Exchange`. Such connection may not hold the proper MetricCollector and can be cached, leading to missed metrics information. This commit moves the configuration of RabbitMQ metrics to a BeanPostProcessor so that the proper MetricCollector is configured before any connection is created. Closes gh-12855pull/13211/head
