Sets up OpenTelemetry integration for nar-bridge. Right now it will
export spans for HTTP server requests and all gRPC client requests.
Having the spans available will make performance work significantly
easier as it provides a high level overview of where time is being
spent.
In the future we can add application-specifc metrics and
integrate logrus.

Rename the nar-bridge CLI to nar-bridge-http, because it's the one
spinning up an http server.
