test: add jaeger docker image with HANA trace information

[BobdenOs]

This PR adds a jaeger and prometheus docker image to the hce docker setup. This allow the HANA Cloud instance to share its trace information with the jaeger Open Telemetry trace APIs. The value that the prometheus image provides is the ability to use the monitoring view of jaeger. Which aggregates the trace information to highlight possible performance pain points.

By leveraging @cap-js/telemetry, SAP Passport and HANA traces. It is possible to get a full stack performance overview while in a local development environment. Which is usually only possible in productive landscapes by using dynatrace. By having the detailed trace information locally it enables experimental analysis which is not possible in productive landscapes. Additionally removing the hyper scaler from the equation reduces the number of un controllable factors from the measurement (e.g. noise neighbors, network latency, etc.).

This feature combined with explain (#462) create a powerful foundation for ensuring a good performance base line and analysis of poor performing requests.

Sounds good. Would love to try it out but the hce image doesnt run on ARM macs… could I also attach this to a remote HANA?

The otel.sh script requires ssh access to the HANA machine. For HANA Cloud instances the same functionality is available in dynatrace. The majority of the information (the blue bars) are generated by @cap-js/telemetry which work for all @cap-js/db-services. Which can be ran directly with the jaeger docker configuration.
