Modifying the GUI Server and REST API Server Ports

Due to a defect of LKWMC v1.1.0, the GUI Server and REST API ports cannot be changed in /etc/default/LifeKeeper.
As a workaround, configure the desired ports via the following command instead of configuring them in /etc/default/LifeKeeper. Restart the REST API Server and the GUI Server services once the ports have been configured via systemd environment variables.

# systemctl set-environment WEBUI_PORT=<TCP port number of the GUI server> RESTAPI_PORT=<TCP port number of the REST API server>
# systemctl restart lifekeeper-api lifekeeper-wmc
