Returns:
    List of server names

Important: For any deployment-related task, this function should be called first instead of directly using search_jobs.
This function returns a pre-configured scenario list, each containing the correct server and job path configuration.

Returns:
    List of scenarios, each containing:
        - index: Scenario index (string)
        - name: Scenario name

        - server: Jenkins server name
        - job_path: Job path

Workflow:
1. Call this function to get the scenario list
2. Let the user select a scenario
3. Use search_jobs_by_scenario(scenario) to get the specific job
4. Use trigger_build() to execute deployment

Args:
    scenario: Scenario name or index

Returns:
    List of job info matching the scenario

Note: For deployment tasks, it is recommended to use get_scenario_list() and search_jobs_by_scenario().

Args:

    keyword: Search keyword

Returns:
    List of matching jobs

Args:
    server_name: Jenkins server name
    job_full_name: Full job name
