lib process servers without arguments
All servers that use CPL architecture (D2, CA, netconf) are unable to print out usage information when run without any parameters. Instead, they print out cryptic error message as shown below:
2018-10-01 22:28:51.285 FATAL [kea-ctrl-agent.dctl/23508] DCTL_PID_FILE_ERROR
Control-agent could not create a PID file: Daemon::makePIDFileName config file name is not set
Service failed: Launch failed: Daemon::makePIDFileName config file name is not set'''
