* rename batches property of Trace to ResourceSpans to be OTEL compatible * added test to assert that the response hasn't change * update test data * fix unmarshall test * changelog * fix e2e * try to fix flaky test * create helper functions to marshal and unmarshal traces to OTEL compatible schema * added better documentation
