Prometheus Metrics

DocGraf can be configured to expose Prometheus Metrics. The metrics exposed are grouped into two categories:

1. docgraf_docker_events_recv
   1. This metric will always capture all received events from the Docker daemon
2. docgraf_docker_events_recorded
   1. This metric will be a subset of docgraf_docker_events_recv, it is only the events that were recorded as Annotations

Both metrics expose the following labels:

1. Event Type
2. Event
3. Container
4. Image
5. Image Tag
