Provide detailed memory metrics via prometheus plugin #11743
Description
Is your feature request related to a problem? Please describe.
Hey everyone, we are currently working on replacing the soon-to-be EOL https://github.com/kbudde/rabbitmq_exporter with the built-in prometheus plugin. With that exporter it was possible to get detailed memory statistics from the management plugin, which have helped us debug issues:
https://github.com/rabbitmq/rabbitmq-server/blob/main/deps/rabbitmq_management/priv/www/js/tmpl/memory.ejs#L9-L31
Unfortunately I was unable to get these metrics from the prometheus plugin, the only thing that came close was process_resident_memory_bytes (https://github.com/rabbitmq/rabbitmq-server/blob/main/deps/rabbitmq_prometheus/src/collectors/prometheus_rabbitmq_core_metrics_collector.erl#L72)
