Monitoring template yml file suggestion

监控模板yml文件建议

自定义监控模板yml文件配置过于复杂，建议开发者们提供个自定义监控模板yml共享平台，可以让用户上传自己配置好的 yml文件让更多用户更快捷方便监控各种平台资源，谢谢！

The issue proposes a shared platform where users can upload and reuse custom monitoring YAML templates, but it names no files, tests, or entry points. First clarify the platform’s scope and integration with HertzBeat; done should include an agreed design and a defined way for users to publish and consume templates.
