Describe the change

Adds OpenTelemetry integration to the backend. Allows end-users to view traces for requests processed by Strelka.

Adds a Jaeger all-in-one container for trace visualization.

Converts backend config parsing to a class BackendConfig to improve code re-use.

Modify __main__.py and strelka-backend to support BackendConfig class.

Move coordinator setup from strelka-backend to Backend class.

Removes the deletion of setuptools at build time, it's a runtime dependency.
