Instrumentation Won't Instrument Itself

In previous releases, the instrumentation would instrument itself. So, for example, the HTTP requests that send telemetry to a remote ingest point, such as the New Relic ingester, would also get instrumented. This leads to data ingest that one doesn't usually care about. i.e. you don't usually want to see the spans for the process of delivering the spans to your observability platform. This release implements the Spec required ability to mark spans as non-recording. This can be used by instrumentation to mark areas where any generated spans must be discarded. This release also has improved documentation.
