Requesting allowing infinite timeouts

[dukarc]

I.e. could we allow job_timeout_seconds the ability to accept -1 as infinity timeframe. We would prefer to manage timeouts on the airflow side.

RAY_TASK_CONFIG = {
    "conn_id": CONN_ID,
    "runtime_env": {"working_dir": str(FOLDER_PATH)},
    "poll_interval": 5,
    "job_timeout_seconds": -1, 
    "ray_cluster_yaml": str(RAY_SPEC),
    "xcom_task_key": "dashboard",
}
