Add Test and fix potential bug

MDOJ

Performance-oriented contest management system for IOI like contest

🚧 work in progress, please wait until first release

🪶Lightweight: Only 50MB for the binary(~~plugin is very large~~)
⚡Lighting fast: Using Rust+Grpc-Web and correct implementation/algorithm
🚀Easy to use: By using docker compose, you can setup the system in minutes
⏱️Accurate: Directly use cgroupv2(no docker in judger), Report time deviation to frontend
🔒Secure: Using nsjail to sandbox user submitted code

🐳Scalable: When deployed in cluster, you can scale the system to satisfy reasonable request.
🗄️Extensible: You can add any programing language by placing a *.lang file in plugins folder
🔭 Powerful metrics/tracing using Open-Telemetry

Copy docker/quickstart file to your server and run docker compose up -d, then open https://localhost in your browser.

Because we use grpc-web(server-side stream), HTTP2 is required, you can ignore it or place cert and key in ./cert folder.

login as admin@admin and start play arounds.

See wiki for more details.

Please download source code from release

If you prefer to use default config, you can skip step 2 and 3.

Then start reading documents in subfolder of your interest.

you may need to run just prepare in judger, backend subfolder.

Set CONFIG_PATH to change the path to config file, default value is config.toml

	/// this will try to add token to request.
	///
	/// If token is not exist, it will just ignore error and return request without token
	fn with_token(self, token: String) -> Request<Self>;
