As part of our integration of OpenTelemetry we want to expose prometheus metrics to the OTEL Collector.

Acceptance criteria

• Collector receives metrics from all prometheus targets.

ToDo

• Task definition for OTEL ECS service updated to include prometheus service discovery side-car for scrape_configs
• Use/repurpose this code to set up prometheus service discovery.
• Add prometheus receiver to OTEL config
• Setup TLS in IaC (not required)
