建议添加gateone说明，以解决：Unit gateone.service not found问题

[atompi]

Ubuntu 16.04系统环境下，启动gateone service会报错：Unit gateone.service not found，可用如下方式解决：

添加/lib/systemd/system/gateone.service

[Unit]
Description=Web-based terminal

[Service]
Type=simple
PIDFile=/tmp/gateone.pid
WorkingDirectory=/var/lib/gateone
ExecStart=/usr/local/bin/gateone
Restart=on-abort

[Install]
WantedBy=multi-user.target

@mission802 谢谢，我把这个issues更新到gateone安装文档里面作为常见问题指引。
