    [TestRail] Wait up to 10 min for API is up

    Since time to time TestRail goes down (service
    unavailable error is recieved on all requests),
    added 503 code to known errors and 10 retries w/
    60 seconds sleep for such cases.

    Default sleep value was increased from 5 to 60
    seconds, because 429 error is always returned
    w/ 'retry-after' header, so it will be used
    for handling 503 error only.
