Missing support for API routes

In the manifest yaml file it is possible to define alternative routes with params
note: The cli does not output these urls after a successful build/deploy/run, and they are not currently added to config.json

Our localhost express server should handle these routes, and map them to the correct actions with params.

从 manifest YAML 处理、config.json 生成以及 dev 命令使用的 localhost Express 服务器入手。跟踪一次成功的 build、deploy 或 run，了解 URL 在哪里报告以及路由在哪里配置。完成的标准是，参数化的备用路由出现在 config.json 和 CLI 输出中，并且本地服务器将它们映射到正确的操作。
