OneCollector exporter reads unbounded HTTP response bodies

Summary When exporting telemetry to a back-end/collector over HTTP using the OpenTelemetry.Exporter.OneCollector exporter, if the request results in a unsuccessful request i.e. HTTP 4xx or 5xx, the response is read into memory with no upper-bound on the number of bytes consumed. This could cause...
