The default tracer should be picked up at configuration creation time from the bootstrapped one, so we don't have to manually configure it in the simplest cases. It is possible to disable it by explicitly setting `nil` on the tracing configuration, even if the global tracer was bootstrapped.

## Motivation `AsyncHTTPClient` recently gained built-in support for Distributed Tracing (swift-server/async-http-client#857, swift-server/async-http-client#861, swift-server/async-http-client#862). It'd be a great showcase of Distributed Tracing to have an "end-to-end" example involving two server communicating via HTTP and this is now achievable without any manual HTTP client instrumentation. We already have multiple demos for both Vapor and Hummingbird so it feels natural for this demo to exist in Swift OTel as well. ## Modifications - Adds an example with two HTTP servers (Hummingbird & Vapor) where one calls the other via `AsyncHTTPClient` ## Result We now have an example that spans (no pun intended) two servers, connected via `AsyncHTTPClient`.
