Update plugin for RabbitMQ Managment 3.8.0

[sfoxdev]

Trying to use plugin 3.7.9.1 for RabbitMQ Managment 3.8.0 but it not works.
On pluging enable getting error:

As of 3.8.0, RabbitMQ ships a built-in rabbitmq_prometheus plugin, no extra plugins required: https://www.rabbitmq.com/prometheus.html

[sfoxdev]

Thank you @gerhard , but I want to use this plugin, not native.

[gerhard]

3.7.9.1 is incompatible with RabbitMQ 3.8.x, which makes it a great opportunity to contribute.

It may be as simple as removing one of the prometheus-4.3.0.ez files, which means that the contribution is a documentation change.

I encourage you to give it a go! 👍

Thanks for this, @gerhard. But I couldn't find metrics specific to the queue, e.g., rabbitmq_queue_messages_delivered_total. Is there a way to enable this on the built-in plugin?

go Services and restart the RabbitMQ.
