GitHub issue: [#12765](https://github.com/rabbitmq/rabbitmq-server/pull/12765)

* New metric: `queue_identity_info`.

`queue_identity_info` is a new metric whose labels describe the type
of the queue and its membership status (leader/follower) on the scraped node.

GitHub issue: [#13583](https://github.com/rabbitmq/rabbitmq-server/pull/13583)

* `rabbitmq_identity_info` now includes a new label, `rabbitmq_endpoint`.

The label allows operators differntiate between metrics scraped from different
RabbitMQ endpoints (the per-object one and the aggregated one).

Since some metric names are identical regardless of whether they were
scraped from `/metrics` and `/metrics/per-object`, scraping both endpoints could lead to
duplicates and confusion.
