JsonTraceViewer

Honestly, who did never dream to see messages content in JSON instead of XML in Visual Trace ?
This app made it real.

• Suitable idea to view the messages in JSON format.
• It really helps to whenever we need to take a look of the JSON structure.
• works fine without troubles

Docker worked smoothly
Nice idea to view message content as JSON
Well organized code
Production worked fine

• the docker image builds fast and starts well (after my PR)
• The decription is complete and convincing
• nice to see not just the traditional format
• but also the new one
• that's convincing
