initializePropagators

public static io.opentelemetry.context.propagation.ContextPropagators initializePropagators(List<String> propagatorIds)

Initialize OpenTelemetry global Propagators with propagator list, if any.

Because TraceMultiPropagator returns first successful extracted Context and stops further extraction, these rules are applied:

• W3CBaggagePropagator and JaegerPropagator are added outside of the multi-propagator so that they will always runs and extract baggage (note: JaegerPropagator extracts both baggage and context).
• W3CBaggagePropagator comes after JaegerPropagator, as it can have more complex/complete values that Jaeger baggage lacks, e.g. metadata. Baggage extraction can enrich the previous one.
