Description

The goal of the ticket is to remove the YAML based flow config generation and use the flow.json based configuration like in NiFi.

This involves:

• removing the YAML ConfigTransformer and all related classes
• use flow.json in all flow ingestor methods and C2 flow update
• creating a dedicated minifi.properties instead of generating on the fly
• adjust the property update command to work with the new approach
• modify C2 server to send flow in JSON format
