Currently, the launcher first notifies systemd, then starts checking the services (RPC and WSGI). So any failures will be reported, but only after systemd declares the service ready. This change adds a polling loop to make sure RpcService.start() finishes successfully. Change-Id: Ib460622d69a9cb1cb82e796a6ab294bbbb40c359
