feat: add check graph cmd and integration tests

[leoadonia]

1. 命令行如下:

   Check the predefined graph or start_graph cmd for the primary app. For more detailed usage, run 'graph -h'
   
   Usage: tman check graph [OPTIONS] --app <APP>
   
   Options:
         --app <APP>
             The absolute path of the app declared in the graph. By default, the predefined graph will be read from the first one in the list. 
         --predefined-graph-name <PREDEFINED_GRAPH_NAME>
             Specify the predefined graph name only to be checked, otherwise, all graphs will be checked.
         --graph <GRAPH>
             Specify the json string of a 'start_graph' cmd to be checked. If not specified, the predefined graph in the primary app will be checked.
     -h, --help
             Print help

2. 增加 Graph 中 Node/Connection 中 app 校验, 不能为 "localhost". 只能为空或者其他值.

3. 如果 _ten::uri, Graph 中的 Node/Connection 中的 app 为空或者 localhost, dump property 时不会保存.
