Check if the cb-network agent can run on CentOS7

[yunkon-kim]

I want to simply check if the cb-network agent could be running or not.

The service file should be updated.

• Service file paths are different on Ubuntu and Centos.
• ExecStop would be required for the graceful shutdown.

The path and content of the service file

cat <<EOF | sudo tee -a /etc/systemd/system/cb-network-agent.service
[Unit]
Description=Service of cb-network agent

[Service]
Type=simple
ExecStart=${HOME}/cb-network-agent/run-cb-network-agent.sh
Restart=on-failure
