The scripts for different projects are placed under different hierarchical directories. For example, as follows, there may be script dependencies in folder 2, and whether folders and script dependencies can be supported at present.
                Folder 2.1
File 1--"Box 2.2-------" File 3
               Folder 2.3

     不同的项目的脚本放在不同的分层目录下面，举个例子 如下，可能文件夹2中还有脚本的依赖，目前能否支持文件夹和脚本的依赖。

Introduce new command that read/tail error/info log

Possible read commands:

• leprechaun error-log
• leprechaun info-log

Possible tail commands:

• leprechaun tail-error-log
• leprechaun tail-info-log

These commands will try to read global error and info logs if they are specified as global. Every service can have it's own error and info log so we should include default commands in age
