* Add new propagators package * Move B3 propagator to propagators Update all `api/trace` dependencies in the propagator. Export the isDeferred and isDebug methods of the SpanContext. These are needed by the B3 propagator to track trace state. * Move W3C trace context propagator to propagators * Update package docs with supported encodings * Move unified propagators code to own file * Update b3 exported documentation * Update trace_context exported documentation * Add code examples for B3 propagator * Add TraceContext example code * Remove internal package Move common testing declarations to the propagators_test.go file. * Add changes to Changelog * Add test to check default propagators
