Prometheus Exporter

An output plugin to expose Prometheus Metrics
The prometheus exporter allows you to take metrics from Calyptia Fluent Bit and expose them such that a Prometheus instance can scrape them.
Important Note: The prometheus exporter only works with metric plugins, such as Node Exporter Metrics
