Tracing Calls Through Backend Components

The goal of the project is to implement distributed tracing in order to trace individual calls between multiple backend components. The implementation can be broken down into the following stages: Infrastructure: Deploy an OpenTelemetry colector, and a Tempo tracing backend; Instrumentation: Instrument backend components in order to send events to the collector; Tracing: Stitch events together into traces by propagating trace context; Polishing: Iterate the generated events in order to improve the observability of the system; Documentation: Document how to deploy the required components, how to add/modify generated events, and how to visualize the data.
