Add indicator if SpanContext was propagated from remote parent (open-telemetry#516)
According to the spec a SpanContext should have an indicator if it was propagated from a remote parent. Introduces an is_remote flag on the SpanContext which gets set when the SpanContext is extracted in a propagaton.
