As an engineer I would like to trace calls in on-demand.

See 'otel-tracing-library' draft MR in structured-data for more details.

Todo:

• Commit submodules with OTEL integrated
• Create tracing library constructor in dependency injection libraries
• Inject Tracer into Subscriber
• Ensure graceful shutdown of OTEL resources
• Expose prometheus port in IaC
• Add standard prometheus metrics (go collector and process collector)
• Enable Service Discovery for event-bridge handlers in IaC
• Modify unit tests

QA:

• Observe metrics in Grafana
• Observe traces in X-Ray
