Add submission checker for power submission

[pgmpablo157321]

• Check folder structure
• Check file names + check no file is missing (#switches & #nodes)
  • Possibly check with system configuration files
  • Alternatively check that number of files (#switches & #nodes) is the same and from 1 to n
• Check keys + format inside power log files

I have verified this one, and I believe it can be merged as all the behaviors are expected without issue.

Below are what I had tested:

1. If only 1 sw_0.txt file (the record for switch power) is missing. The output is correct, checker will have a warning message and still accept the results based on the Olympic scoring rule.
   

2. If missing 2 sw_0.txt file. Error message got generated as expected.
   

3. It is not a bug, but I'd like to mention it: the checker will give the power folder a warning message, just like it did on the scaling.json file. This is not an issue, I believe the current way will work.
   
   

Thanks,
Frank
