[feature request] provide functionality via a propagator

Component

OpenTelemetry.Instrumentation.AWS

Is your feature request related to a problem?

No response

What is the expected behavior?

If data is being injected/extracted from the context then it should be done via a propagator rather than a method in the execution path. This would enable the Amazon transaction id to be injected into a span by simply adding the propagator.

Which alternative solutions or features have you considered?

Leaving it as it is
