tracing: pipeline_handler: Queue Requests
Add tracing to the base pipeline handler class to track when requests are queued.
Tracing is already available for other Request operations, but queuing a Request
is not an operation handled by the Request itself.
Add the tracepoint to the PipelineHandler::queueRequest() so the lifetime of a
Request can be viewed when tracing.
