Investigate if we should switch to supervisord

[fstab]

The Docker image runs multiple services (OTel collector, Prometheus, Loki, Tempo, Grafana).

Currently we use run-all.sh as a wrapper script to run all of these services.

supervisord is a more sophisticated solution to run multiple services. We should investigate whether it's worthwhile to switch to supervisord.

Instead of supervisor you could also take a look at https://github.com/just-containers/s6-overlay because you don't have a dependency to Python.

Also I was wondering why using redhat/ubi8 as baseimage? For example Grafana itself is using: alpine:3.19.1, that could get the image size down.

Could use something like goreman to have a single binary and just execute a Procfile.
