Support service restart

Registered by Lianhao Lu

Sometimes, the operators might want to the change some configurations(i.e. configuration file) and restart an openstack service without going to the console to CTRL+C to stop the running service and start it again. They might just want to send a signal(i.e. SIGUSR1) to trigger the service to restart by itself to reload new configurations.
