docker-compose: add otel-collector by default, disable jaeger by default (#848)

Removes Jaeger from the default docker-compose deployment, and replaces it with OpenTelemetry Collector configured to log data only.

With the jaeger/docker-compose.yaml overlay, a Jaeger instance can be deployed and otel-collector will be configured to send traces to the deployed Jaeger instance.
