OpenTelementry

[ostcar]

The production environment should start a collector service and a jaeger service.

I think, for the beginning it is ok to start the all-in-one-jaeger-service that only holds the data in memory. After this is done, we can think about saving the spans on disk.

A few thoughts:

1. The OpenTelemtry services should be optional, either as a single feature (enableOpenTelemetry) or individually (enableOpenTelemetryCollector etc.).
2. The Web UI should be available under the main instance domain, e.g., https://example.com/jaeger/, not on a separate port.
3. The Web UI must require authentication (probably using a new Docker secret).
