[TASK] Create a Grafana dashboard utilizing the relayer metrics

[shekohex]

Overview

After working on #387, we should work on a Metrics Dashboard for better understanding how the relayer performs and the other areas where we collect metrics, we need a simple way to visualize these metrics; so that we would make use of https://grafana.com/ dashboards.

Task Checklist

• Run Grafana locally (using docker if possible)
• Run the relayer locally with Local EVM network setup + Local Tangle Standalone
• Start using the relayer locally by sending some transactions (optional)
• Integrate the Relayer metrics into the grafana dashboard.
• Create a dashboard that shows all the supported metrics that are exported by the relayer.
• Export the dashboard for future usage.

First steps are finished, there is now a working Prometheus/Grafan setup which shows a single metric as demonstration. Next step is to build the actual dashboard. You say that it should show all supported metrics but that is pretty vague. Is there maybe an existing Grafana dashboard for a similar project that I could use as reference?

If it is a chore task, we can allocate someone else to do it, but for now showing an example is good.
