Allow passing future values of known_covariates to TimeSeriesCloudPredictor.predict

[shchur]

Currently predict and predict_real_time methods of the TimeSeriesCloudPredictor do not accept the future values of known covariates, which is a major difference from the TimeSeriesPredictor API. We should allow users to pass future values of known covariates at predict time.

Hi any updates on this? predict_real_time does accept kwargs, but they are not actually passed through to the function.
