Share TLS config with the Prometheus plugin #479
Description
Is your feature request related to a problem? Please describe.
In #267, we shared TLS config provided in the custom resource spec to enable TLS for plugins - management, mqtt, stomp, web_mqtt, and web_stomp. Here, we missed the Prometheus plugin.
Prometheus does support connecting over TLS: https://www.rabbitmq.com/prometheus.html#tls
Describe the solution you'd like
Similar implementation pattern as #267.
