* setup sdk exporter package * use sdk exporter package in sdk trace * use sdk exporter package in all exporters * empty the exporters list before testing Load * move SpanData to the exporter package * use the SpanProcessor registration, don't register exporters * rename exporter structs to avoid stutter * rename Syncer and Batcher to SpanSyncer and SpanBatcher So it's explicit they are for spans, and we reduce the risk of name conflict * remove not moot todo * rename sdk exporter to export * only execute the SpanData if it is sampled
