Add missing metrics on Grafana dashboard

Since NXP-26248 deploying a graphite/grafana stack is as easy as:

cd nuxeo-runtime/nuxeo-runtime-metrics/docker/graphite-grafana/
docker-compose up -d

Then configure your nuxeo.conf to report metrics and restart Nuxeo:

metrics.graphite.enabled=true
metrics.graphite.host=localhost
metrics.graphite.port=2003
metrics.graphite.period=60
metrics.tomcat.enabled=true
metrics.log4j.enabled=true

And go to http://localhost:3000/ you should have a Nuxeo grafana dashboard provisioned.

The Nuxeo streams latency requires to run a collector

# kafka example log lag and latency every minute
./bin/stream.sh monitor -k -l ALL -i 60

The goal of this ticket is to complete the default dashboard so it can be used as a default one for debugging and support and serve as a model to show available metrics.

The dashboard is focused on metrics exposed by Nuxeo, other system or service monitoring can be added later as new dashboard tied to their collectors like a Diamond or netdata dashbaords.

Today the dashboard is composed of sections (Visit the the snaphot link to have an overview)

• Logs(5 panels) for apache logs stats
• JVM(6 panels)
• Tomcat(4 panels)
• Nuxeo Repository(6 panels)
• Nuxeo Elasticsearch(4 panels)
• Nuxeo WorkManager(5 panels)
• Nuxeo Audit (TODO)(0 panels)
• Nuxeo Streams (TODO)(3 panels)
• Nuxeo Misc(4 panels)

Some sections need to be completed or added (DBS and VCS may need different sections)
