    ''''Returns an iterator yielding an application\'s request and application logs.
    Logs will be returned by the iterator in reverse chronological order by
    request end time, or by last flush time for requests still in progress (if
    requested).  The items yielded are RequestLog objects, the contents of which
    are accessible via method calls.
    All parameters are optional.
    Args:
    start_time: The earliest request completion or last-update time that
    results should be fetched for, in seconds since the Unix epoch.
    end_time: The latest request completion or last-update time that
    results should be fetched for, in seconds since the Unix epoch.
    offset: A byte string representing an offset into the log stream, extracted
    from a previously emitted RequestLog.  This iterator will begin
    immediately after the record from which the offset came.
    minimum_log_level: An application log level which serves as a filter on the
    requests returned--requests with no application log at or above the
    specified level will be omitted.  Works even if include_app_logs is not
    True.  In ascending order, the available log levels are:
    logservice.LOG_LEVEL_DEBUG, logservice.LOG_LEVEL_INFO,
    logservice.LOG_LEVEL_WARNING, logservice.LOG_LEVEL_ERROR,
    and logservice.LOG_LEVEL_CRITICAL.
    include_incomplete: Whether or not to include requests that have started but
    not yet finished, as a boolean.  Defaults to False.
    include_app_logs: Whether or not to include application level logs in the
    results, as a boolean.  Defaults to False.
    module_versions: A list of tuples of the form (module, version), that
    indicate that the logs for the given module/version combination should be
    fetched.  Duplicate tuples will be ignored.  This kwarg may not be used
    in conjunction with the \'version_ids\' kwarg.
    version_ids: A list of version ids whose logs should be queried against.
    Defaults to the application\'s current version id only.  This kwarg may not
    be used in...'''
