Custom HTTP header for trace ID

[nestorsokil]

Hey, I was wondering how I can supply my own propagator implementation to the agent?
What I want to do is to accept trace ID from a custom HTTP header and then propagate to downstream services using the B3 standard.

Or is the custom propagator a wrong solution for this? I basically just need to use a custom header to seed the trace and then use the regular b3multi.

Custom propagator seems like the correct solution. Unfortunately currently there is no way to supply one to the agent. Can you please open an issue to add such extension point?
