支持自定义节点名称及更多设置 Support for custom node names

[rong6]

CN: 优秀的项目！目前节点名称仅能跟随服务器主机名，我希望可以自定义节点名称以及更多设置，具体可以参考哪吒监控。

EN: Excellent project👍🏻! Currently the node name can only follow the server hostname, I would like to be able to customize the node name and more Settings, See nezha for details.

we have plan to allow people edit it in UI, but now you can config it in cli app with params.

for example

./tianji-reporter --name=fooo
