Support more languages of Casbin, like Go Casbin

For Go Casbin, it can be called via Casdoor API: https://casdoor.org/docs/permission/exposed-casbin-apis , these demo sites can be used: https://door.casdoor.com/, https://demo.casdoor.com/

For other Casbin like Java, Python, etc., we may need to add the CLI interface first (WIP now)
