Autoconfigure Micrometer connection metrics like Rabbit MQ does

[desprez]

Hello
great job for this : it's very usefull.

I want to know if it possible to add some connections metrics in MQAutoConfiguration like RabitMQ does :

https://github.com/spring-projects/spring-boot/blob/main/spring-boot-project/spring-boot-actuator-autoconfigure/src/main/java/org/springframework/boot/actuate/autoconfigure/metrics/amqp/RabbitMetricsAutoConfiguration.java

https://github.com/rabbitmq/rabbitmq-jms-client/blob/main/src/main/java/com/rabbitmq/jms/admin/RMQConnectionFactory.java

The queue manager already produces a whole load of metrics including connection request counts. That's not something I'd expect to then also have in a specific client library with yet another way to interrogate it. There are many tools available to collect and display those queue manager metrics - see for example the amqsrua sample program, the Grafana interfaces here, the documented Accounting and Statistics events ...
