Currently, there is no way to set up an exclusive propagator for gRPC instrumentation, except using the global propagator.
Here is the scenario, I like to use
B3propagator to be compatible with other tracing systems, which should only affect gRPC header. But using a global propagator will influence all propagators.So I add options for gRPC instrumentation to achieve this.
