The function of class "ProcessLauncher" is to fork multiple processes. the function of "WorkerService.start" is provider api service and set process title according to the parameter desc. when multiple API processes need to be launched, use "ProcessLauncher" (in module oslo_service.service) manage. call "ProcessLauncher.launch_service" with the num of processes and service instance to real launch. when the "ProcessLauncher" launch the service, it calls the "start" method of the service directly without passing any parameters. Starting API processes, the service object passed in is WorkerService (in module neutron.wsgi) object. In the current design, pass the "desc" in call "WorkerService.start", therefore, the desc cannot be set. This patch add the "desc" parameter to the initialization, when call "start" method, if set "desc", it will be used first. if not, "desc" passed in initialization are used. this design solves the problem and keeps compatibility.
