How to get the total cost of executing a cloudlet?

[zijie1024]

By reviewing the Cloudlet source code, I found that the getProcessingCost() function's return value only includes bandwidth cost, even though the comments state it includes processing cost. If I want to get the total cost, including CPU, Memory, Storage, and Bw, how should I do it? Is there an existing method? If not, should a new method be considered in the future, and how can I get the total cost now?

Feel free di propose a change to that function and I will review it, all the ingredients to make it work are there
