CCO: predict the future spot interruption rates

[ilya-kolchinsky]

Different spot instance types are characterized by different interruption rates which are subject to change over time. When considering the reliability of the proposed deployment (#40), the optimizer should consider the future projected interruption rates. To that end, a time series forecasting solution utilizing historical data to predict future trends has to be implemented.

Next, examine the mechanism by which the optimizer will not necessarily offer the cheapest instance, but the most efficient one - which its cost will be greater per hour of work, but it will work in less time than the cheapest instance.

This is not related to this issue and should be stated as a separate one.
