Change the format of rest response for v1.py

Hi DMTF,

I use this python library to develop a robot automation test framework.
From this part of "v1.py".

Can someone change the response as a Json format?
I think this is useful if anyone try to analyze the report.

Below is the coding example that I try to show as a json format to the report.

I think that would be a useful change. Would you be willing to make a pull request with the changes?

Sure, but let me try if any side effect first.
