Handle generalizes the handling of lambda inputs.

Run will create a new fx app and run it, passing any exit code to os.Exit.

RunApp runs an fx app in a Lambda environment.

RunNewApp will create an fx App and calls RunApp with the handler and options populated from the fx dependencies.

WithLogger decorates the context with a zap handler that logs each with the request id and other lambda information.

Context interface with extra components that we want to use across our lambda functions.
