- feature: added python runner

[agallardol]

Added PythonRunner, it shares the same rules as DenoRunner

    let code_files = CodeFiles {
        files: HashMap::from([(
            "main.py".to_string(),
            r#"
import requests
def run(configurations, parameters):
    response = requests.get('https://httpbin.org/get')
    return response.json()['url']
                "#
            .to_string(),
        )]),
        entrypoint: "main.py".to_string(),
    };

    let python_runner = PythonRunner::new(
        code_files,
        Value::Null,
        Some(PythonRunnerOptions {
            ..Default::default()
        }),
    );

    let result = python_runner
        .run(None, Value::Null, None)
        .await
        .unwrap();

    assert_eq!(result.data.as_str().unwrap(), "https://httpbin.org/get");
