chore: move baggage methods in propagation namespace

README.md

@@ -111,6 +111,7 @@ Because the npm installer and node module resolution algorithm could potentially
 - `HttpBaggage` renamed to `HttpBaggagePropagator`
 - [#45](https://github.com/open-telemetry/opentelemetry-js-api/pull/45) `Span#context` renamed to `Span#spanContext`
 - [#47](https://github.com/open-telemetry/opentelemetry-js-api/pull/47) `getSpan`/`setSpan`/`getSpanContext`/`setSpanContext` moved to `trace` namespace
+- [#55](https://github.com/open-telemetry/opentelemetry-js-api/pull/55) `getBaggage`/`setBaggage`/`createBaggage` moved to `propagation` namespace
