feat(docker): add full grafana, prometheus, tempo setup for local dev

This is a very useful stack for local development as well, by allowing
to easily access a local grafana instance and look at the accessed
endpoints, query usage and durations etc.
As a nice side effect this also makes sure we have an easy way to
actually test any changes to the opentelemetry integration in an actual
environment instead of just listening to a raw socket.
